To make the test more robust, there are the following changes:
1. add a check for the return value of kmem_cache_alloc().
2. properly release the object `buf` on several error paths.
3. release the objects of `used_objects` if we never hit `saved_ptr`.
4. destroy the created cache by default.

Patch series "Convert vmcore to use an iov_iter", v5.
For some reason several people have been sending bad patches to fix
compiler warnings in vmcore recently. Here's how it should be done.
Compile-tested only on x86. As noted in the first patch, s390 should take
this conversion a bit further, but I'm not inclined to do that work
myself.
This patch (of 3):
Instead of passing in a 'buf' and 'userbuf' argument, pass in an iov_iter.
s390 needs more work to pass the iov_iter down further, or refactor, but
I'd be more comfortable if someone who can test on s390 did that work.
It's more convenient to convert the whole of read_from_oldmem() to take an
iov_iter at the same time, so rename it to read_from_oldmem_iter() and add
a temporary read_from_oldmem() wrapper that creates an iov_iter.

When list_for_each_entry() completes the iteration over the whole list
without breaking the loop, the iterator value will be a bogus pointer
computed based on the head element.
While it is safe to use the pointer to determine if it was computed based
on the head element, either with list_entry_is_head() or &pos->member ==
head, using the iterator variable after the loop should be avoided.
In preparation to limit the scope of a list iterator to the list traversal
loop, use a dedicated pointer to point to the found element [1].

Patch series "rewrite error handling during mounting stage".
This patch (of 5):
After commit da5e7c8782 ("ocfs2: cleanup journal init and shutdown"),
journal init later than before, it makes NULL pointer access in free
routine.
Crash flow:
ocfs2_fill_super
+ ocfs2_mount_volume
| + ocfs2_dlm_init //fail & return, osb->journal is NULL.
| + ...
| + ocfs2_check_volume //no chance to init osb->journal
|
+ ...
+ ocfs2_dismount_volume
ocfs2_release_system_inodes
...
evict
...
ocfs2_clear_inode
ocfs2_checkpoint_inode
ocfs2_ci_fully_checkpointed
time_after(journal->j_trans_id, ci->ci_last_trans)
+ journal is empty, crash!
For fixing, there are three solutions:
1> Partly revert commit da5e7c8782
For avoiding kernel crash, this make sense for us. We only
concerned whether there has any non-system inode access before dlm
init. The answer is NO. And all journal replay/recovery handling
happen after dlm & journal init done. So this method is not graceful
but workable.
2> Add osb->journal check in free inode routine (eg ocfs2_clear_inode)
The fix code is special for mounting phase, but it will continue
working after mounting stage. In another word, this method adds
useless code in normal inode free flow.
3> Do directly free inode in mounting phase
This method is brutal/complex and may introduce unsafe code,
currently maintainer didn't like.
At last, we chose method <1> and did partly reverted job. We reverted
journal init codes, and kept cleanup codes flow.

This removes the need to use a found variable and simply checking if the

The Time-Specified Departure feature is indeed mutually exclusive with
TX IP checksumming in ENETC, but TX checksumming in itself is broken and
was removed from this driver in commit 82728b91f1 ("enetc: Remove Tx
checksumming offload code").
The blamed commit declared NETIF_F_HW_CSUM in dev->features to comply
with software TSO's expectations, and still did the checksumming in
software by calling skb_checksum_help(). So there isn't any restriction
for the Time-Specified Departure feature.
However, enetc_setup_tc_txtime() doesn't understand that, and blindly
looks for NETIF_F_CSUM_MASK.
Instead of checking for things which can literally never happen in the
current code base, just remove the check and let the driver offload
tc-etf qdiscs.

Because nf_sk_lookup_slow*() assume packet headers are in the

to prerouting, input and output.
Use in output work if a socket is already attached to the skb.

Commit 00bfe02f47 ("gfs2: Fix mmap + page fault deadlocks for buffered
I/O") changed gfs2_file_read_iter() and gfs2_file_buffered_write() to
allow dropping the inode glock while faulting in user buffers. When the
lock was dropped, a short result was returned to indicate that the
operation was interrupted.
As pointed out by Linus (see the link below), this behavior is broken
and the operations should always re-acquire the inode glock and resume
the operation instead.

Calling tls_append_frag when max_open_record_len == record->len might
add an empty fragment to the TLS record if the call happens to be on the
page boundary. Normally tls_append_frag coalesces the zero-sized
fragment to the previous one, but not if it's on page boundary.
If a resync happens then, the mlx5 driver posts dump WQEs in
tx_post_resync_dump, and the empty fragment may become a data segment
with byte_count == 0, which will confuse the NIC and lead to a CQE
error.
This commit fixes the described issue by skipping tls_append_frag on
zero size to avoid adding empty fragments. The fix is not in the driver,
because an empty fragment is hardly the desired behavior.
