Pull btrfs updates from David Sterba:
"This round there are a lot of cleanups and moved code so the diffstat
looks huge, otherwise there are some nice performance improvements and
an update to raid56 reliability.
User visible features:
- raid56 reliability vs performance trade off:
- fix destructive RMW for raid5 data (raid6 still needs work): do
full checksum verification for all data during RMW cycle, this
should prevent rewriting potentially corrupted data without
notice
- stripes are cached in memory which should reduce the performance
impact but still can hurt some workloads
- checksums are verified after repair again
- this is the last option without introducing additional features
(write intent bitmap, journal, another tree), the extra checksum
read/verification was supposed to be avoided by the original
implementation exactly for performance reasons but that caused
all the reliability problems
- discard=async by default for devices that support it
- implement emergency flush reserve to avoid almost all unnecessary
transaction aborts due to ENOSPC in cases where there are too many
delayed refs or delayed allocation
- skip block group synchronization if there's no change in used
bytes, can reduce transaction commit count for some workloads
Performance improvements:
- fiemap and lseek:
- overall speedup due to skipping unnecessary or duplicate
searches (-40% run time)
- cache some data structures and sharedness of extents (-30% run
time)
- send:
- faster backref resolution when finding clones
- cached leaf to root mapping for faster backref walking
- improved clone/sharing detection
- overall run time improvements (-70%)
Core:
- module initialization converted to a table of function pointers run
in a sequence
- preparation for fscrypt, extend passing file names across calls,
dir item can store encryption status
- raid56 updates:
- more accurate error tracking of sectors within stripe
- simplify recovery path and remove dedicated endio worker kthread
- simplify scrub call paths
- refactoring to support the extra data checksum verification
during RMW cycle
- tree block parentness checks consolidated and done at metadata read
time
- improved error handling
- cleanups:
- move a lot of code for better synchronization between kernel and
user space sources, split big files
- enum cleanups
- GFP flag cleanups
- header file cleanups, prototypes, dependencies
- redundant parameter cleanups
- inline extent handling simplifications
- inode parameter conversion
- data structure cleanups, reductions, renames, merges"

Pull VFS acl updates from Christian Brauner:
"This contains the work that builds a dedicated vfs posix acl api.
The origins of this work trace back to v5.19 but it took quite a while
to understand the various filesystem specific implementations in
sufficient detail and also come up with an acceptable solution.
As we discussed and seen multiple times the current state of how posix
acls are handled isn't nice and comes with a lot of problems: The
current way of handling posix acls via the generic xattr api is error
prone, hard to maintain, and type unsafe for the vfs until we call
into the filesystem's dedicated get and set inode operations.
It is already the case that posix acls are special-cased to death all
the way through the vfs. There are an uncounted number of hacks that
operate on the uapi posix acl struct instead of the dedicated vfs
struct posix_acl. And the vfs must be involved in order to interpret
and fixup posix acls before storing them to the backing store, caching
them, reporting them to userspace, or for permission checking.
Currently a range of hacks and duct tape exist to make this work. As
with most things this is really no ones fault it's just something that
happened over time. But the code is hard to understand and difficult
to maintain and one is constantly at risk of introducing bugs and
regressions when having to touch it.
Instead of continuing to hack posix acls through the xattr handlers
this series builds a dedicated posix acl api solely around the get and
set inode operations.
Going forward, the vfs_get_acl(), vfs_remove_acl(), and vfs_set_acl()
helpers must be used in order to interact with posix acls. They
operate directly on the vfs internal struct posix_acl instead of
abusing the uapi posix acl struct as we currently do. In the end this
removes all of the hackiness, makes the codepaths easier to maintain,
and gets us type safety.
This series passes the LTP and xfstests suites without any
regressions. For xfstests the following combinations were tested:
- xfs
- ext4
- btrfs
- overlayfs
- overlayfs on top of idmapped mounts
- orangefs
- (limited) cifs
There's more simplifications for posix acls that we can make in the
future if the basic api has made it.
A few implementation details:
- The series makes sure to retain exactly the same security and
integrity module permission checks. Especially for the integrity
modules this api is a win because right now they convert the uapi
posix acl struct passed to them via a void pointer into the vfs
struct posix_acl format to perform permission checking on the mode.
There's a new dedicated security hook for setting posix acls which
passes the vfs struct posix_acl not a void pointer. Basing checking
on the posix acl stored in the uapi format is really unreliable.
The vfs currently hacks around directly in the uapi struct storing
values that frankly the security and integrity modules can't
correctly interpret as evidenced by bugs we reported and fixed in
this area. It's not necessarily even their fault it's just that the
format we provide to them is sub optimal.
- Some filesystems like 9p and cifs need access to the dentry in
order to get and set posix acls which is why they either only
partially or not even at all implement get and set inode
operations. For example, cifs allows setxattr() and getxattr()
operations but doesn't allow permission checking based on posix
acls because it can't implement a get acl inode operation.
Thus, this patch series updates the set acl inode operation to take
a dentry instead of an inode argument. However, for the get acl
inode operation we can't do this as the old get acl method is
called in e.g., generic_permission() and inode_permission(). These
helpers in turn are called in various filesystem's permission inode
operation. So passing a dentry argument to the old get acl inode
operation would amount to passing a dentry to the permission inode
operation which we shouldn't and probably can't do.
So instead of extending the existing inode operation Christoph
suggested to add a new one. He also requested to ensure that the
get and set acl inode operation taking a dentry are consistently
named. So for this version the old get acl operation is renamed to
->get_inode_acl() and a new ->get_acl() inode operation taking a
dentry is added. With this we can give both 9p and cifs get and set
acl inode operations and in turn remove their complex custom posix
xattr handlers.
In the future I hope to get rid of the inode method duplication but
it isn't like we have never had this situation. Readdir is just one
example. And frankly, the overall gain in type safety and the more
pleasant api wise are simply too big of a benefit to not accept
this duplication for a while.
- We've done a full audit of every codepaths using variant of the
current generic xattr api to get and set posix acls and
surprisingly it isn't that many places. There's of course always a
chance that we might have missed some and if so I'm sure we'll find
them soon enough.
The crucial codepaths to be converted are obviously stacking
filesystems such as ecryptfs and overlayfs.
For a list of all callers currently using generic xattr api helpers
see [2] including comments whether they support posix acls or not.
- The old vfs generic posix acl infrastructure doesn't obey the
create and replace semantics promised on the setxattr(2) manpage.
This patch series doesn't address this. It really is something we
should revisit later though.
The patches are roughly organized as follows:
(1) Change existing set acl inode operation to take a dentry
argument (Intended to be a non-functional change)
(2) Rename existing get acl method (Intended to be a non-functional
change)
(3) Implement get and set acl inode operations for filesystems that
couldn't implement one before because of the missing dentry.
That's mostly 9p and cifs (Intended to be a non-functional
change)
(4) Build posix acl api, i.e., add vfs_get_acl(), vfs_remove_acl(),
and vfs_set_acl() including security and integrity hooks
(Intended to be a non-functional change)
(5) Implement get and set acl inode operations for stacking
filesystems (Intended to be a non-functional change)
(6) Switch posix acl handling in stacking filesystems to new posix
acl api now that all filesystems it can stack upon support it.
(7) Switch vfs to new posix acl api (semantical change)
(8) Remove all now unused helpers
(9) Additional regression fixes reported after we merged this into
linux-next

encouragement and input from Christoph"

Although we have an existing function, btrfs_lookup_csums_range(), to
find all data checksums for a range, it's based on a btrfs_ordered_sum
list.
For the incoming RAID56 data checksum verification at RMW time, we don't
want to waste time by allocating temporary memory.
So this patch will introduce a new helper, btrfs_lookup_csums_bitmap().
It will use bitmap based result, which will be a perfect fit for later
RAID56 usage.

An inode's io_tree can be quite large and there are cases where due to
delalloc it can have thousands of extent state records, which makes the
red black tree have a depth of 10 or more, making the operation of
count_range_bits() slow if we repeatedly call it for a range that starts
where, or after, the previous one we called it for. Such use cases are
when searching for delalloc in a file range that corresponds to a hole or
a prealloc extent, which is done during lseek SEEK_HOLE/DATA and fiemap.
So introduce a cached state parameter to count_range_bits() which we use
to store the last extent state record we visited, and then allow the
caller to pass it again on its next call to count_range_bits(). The next
patches in the series will make fiemap and lseek use the new parameter.
This change is part of a patchset that has the goal to make performance
better for applications that use lseek's SEEK_HOLE and SEEK_DATA modes to
iterate over the extents of a file. Two examples are the cp program from
coreutils 9.0+ and the tar program (when using its --sparse / -S option).
A sample test and results are listed in the changelog of the last patch
in the series:
1/9 btrfs: remove leftover setting of EXTENT_UPTODATE state in an inode's io_tree
2/9 btrfs: add an early exit when searching for delalloc range for lseek/fiemap
3/9 btrfs: skip unnecessary delalloc searches during lseek/fiemap
4/9 btrfs: search for delalloc more efficiently during lseek/fiemap
5/9 btrfs: remove no longer used btrfs_next_extent_map()
6/9 btrfs: allow passing a cached state record to count_range_bits()
7/9 btrfs: update stale comment for count_range_bits()
8/9 btrfs: use cached state when looking for delalloc ranges with fiemap

The extent_io_tree::private_data was meant to be a preparatory work for
the metadata inode rework but that never materialized. Now it's used
only for an inode so it's better to change the appropriate type and
rename it.

All callers except one pass NULL, so the parameter can be dropped and
the inode::io_tree initialization can be open coded.

After previous patches the unused parameters can be removed from
btree_submit_bio_start and btrfs_submit_bio_start as they don't need to
conform to the extent_submit_bio_start_t typedef.

There's a callback function parameter for btrfs_wq_submit_bio that can
be one of: metadata, buffered data, direct io data. The callback
abstraction is unnecessary as we have all functions available.
Replace the parameter with a command that leads to a direct call in
run_one_async_start. The called functions can be then simplified and we
can also remove the extent_submit_bio_start_t typedef.

Compression and direct io don't work together so the compression
parameter can be dropped after previous patch that changed the call
to direct.

There's a function pointer passed to btrfs_repair_one_sector that will
submit the right bio for repair. However there are only two callbacks,
for buffered and for direct IO. This can be simplified to a bool-based
switch and call either function, indirect calls in this case is an
unnecessary abstraction. This allows to remove the submit_bio_hook_t
typedef.
