Merge tag 'ovl-update-6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/overlayfs/vfs
Pull overlayfs updates from Amir Goldstein:
- Overlayfs aio cleanups and fixes
Cleanups and minor fixes in preparation for factoring out of
read/write passthrough code.
- Overlayfs lock ordering changes
Hold mnt_writers only throughout copy up instead of a long lived
elevated refcount.
- Add support for nesting overlayfs private xattrs
There are cases where you want to use an overlayfs mount as a
lowerdir for another overlayfs mount. For example, if the system
rootfs is on overlayfs due to composefs, or to make it volatile (via
tmpfs), then you cannot currently store a lowerdir on the rootfs,
because the inner overlayfs will eat all the whiteouts and overlay
xattrs. This means you can't e.g. store on the rootfs a prepared
container image for use with overlayfs.
This adds support for nesting of overlayfs mounts by escaping the
problematic features and unescaping them when exposing to the
overlayfs user.
- Add new mount options for appending lowerdirs

Here's the second big bcachefs pull request. This brings your tree up to
date with my master branch, which is what existing bcachefs users are
currently running.
All but the last few patches have been in linux-next, those being small
fixes. Test results from my dashboard:
https://evilpiepirate.org/~testdashboard/ci?commit=c7046ed0cf9bb33599aa7e72e7b67bba4be42d64
New features:
- rebalance_work btree (and metadata version 1.3): the rebalance thread
no longer has to scan to find extents that need processing - big
scalability improvement.
- sb_errors superblock section: this adds counters for each fsck error
type, since filesystem creation, along with the date of the most
recent error. It'll get us better bug reports (since users do not
typically report errors that fsck was able to fix), and I might add
telemetry for this in the future.
Fixes include:
- multiple snapshot deletion fixes
- members_v2 fixups
- deleted_inodes btree fixes
- copygc thread no longer spins when a device is full but has no
fragmented buckets (i.e. rebalance needs to move data around instead)
- a fix for a memory reclaim issue with the btree key cache: we're now
careful not to hold the srcu read lock that blocks key cache reclaim
for too long
- an early allocator locking fix, from Brian
- endianness fixes, from Brian
- CONFIG_BCACHEFS_DEBUG_TRANSACTIONS no longer defaults to y, a big
performance improvement on multithreaded workloads

Currently, when the range to flush covers more than one page (a 4K page or
a hugepage), __flush_tlb_range() flushes the whole tlb. Flushing the whole
tlb comes with a greater cost than flushing a single entry so we should
flush single entries up to a certain threshold so that:
threshold * cost of flushing a single entry < cost of flushing the whole
tlb.

flush_tlb_range() uses a fixed stride of PAGE_SIZE and in its current form,
when a hugetlb mapping needs to be flushed, flush_tlb_range() flushes the
whole tlb: so set a stride of the size of the hugetlb mapping in order to
only flush the hugetlb mapping. However, if the hugepage is a NAPOT region,
all PTEs that constitute this mapping must be invalidated, so the stride
size must actually be the size of the PTE.
Note that THPs are directly handled by flush_pmd_tlb_range().

When doing a multishot read, the code path reuses the old read
paths. However this breaks an assumption built into those paths,
namely that struct io_rw::len is available for reuse by __io_import_iovec.
For multishot this results in len being set for the first receive
call, and then subsequent calls are clamped to that buffer length
incorrectly.
Instead keep len as zero after recycling buffers, to reuse the full
buffer size of the next selected buffer.

For addr: this field is not used, since buffer select is forced.
But by forcing it to be zero it leaves open future uses of the field.
len is actually usable, you could imagine that you want to receive
multishot up to a certain length.
However right now this is not how it is implemented, and it seems
safer to force this to be zero.

For the sake of coherency, use local labels in assembly when
applicable. This also avoid kprobes being confused when applying a
kprobe since the size of function is computed by checking where the
next visible symbol is located. This might end up in computing some
function size to be way shorter than expected and thus failing to apply
kprobes to the specified offset.

When flashing loader.bin for K210 using kflash:
[ERROR] This is an ELF file and cannot be programmed to flash directly: arch/riscv/boot/loader.bin

RISC-V Makefile to create a boot image with the right format. With this
removed, the image is now created in the wrong (ELF) format.
Fix this by adding an explicit rule.

only if the size of the region to flush is < threshold * PAGE_SIZE.
