Certain error paths from mlx5_vdpa_dev_add() can end up releasing mr resources which never got initialized in the first place. This patch adds the missing check in mlx5_vdpa_destroy_mr_resources() to block releasing non-initialized mr resources.

errors that are known to always be safe to fix should be autofix: this should be most errors even at this point, but that will need some thorough review. note that errors are still logged in the superblock, so we'll still know that they happened.

We had a report of data corruption on nixos when building installer images. https://github.com/NixOS/nixpkgs/pull/321055#issuecomment-2184131334 It seems that writes are being dropped, but only when issued by QEMU, and possibly only in snapshot mode. It's undetermined if it's write calls are being dropped or dirty folios. Further testing, via minimizing the original patch to just the change that skips the inode lock on non appends/truncates, reveals that it really is just not taking the inode lock that causes the corruption: it has nothing to do with the other logic changes for preserving write atomicity in corner cases. It's also kernel config dependent: it doesn't reproduce with the minimal kernel config that ktest uses, but it does reproduce with nixos's distro config. Bisection the kernel config initially pointer the finger at page migration or compaction, but it appears that was erroneous; we haven't yet determined what kernel config option actually triggers it. Sadly it appears this will have to be reverted since we're getting too close to release and my plate is full, but we'd _really_ like to fully debug it. My suspicion is that this patch is exposing a preexisting bug - the inode lock actually covers very little in IO paths, and we have a different lock (the pagecache add lock) that guards against races with truncate here.

io_provided_buffers_select() returns 0 to indicate success, but it should be returning 1 to indicate that 1 vec was mapped. This causes peeking to fail with classic provided buffers, and while that's not a use case that anyone should use, it should still work correctly. The end result is that no buffer will be selected, and hence a completion with '0' as the result will be posted, without a buffer attached.

It is not safe to dereference fl->c.flc_owner without first confirming fl->fl_lmops is the expected manager. nfsd4_deleg_getattr_conflict() tests fl_lmops but largely ignores the result and assumes that flc_owner is an nfs4_delegation anyway. This is wrong. With this patch we restore the "!= &nfsd_lease_mng_ops" case to behave as it did before the change mentioned below. This is the same as the current code, but without any reference to a possible delegation.

For buffer registration (or updates), a userspace iovec is copied in and updated. If the application is within a compat syscall, then the iovec type is compat_iovec rather than iovec. However, the type used in __io_sqe_buffers_update() and io_sqe_buffers_register() is always struct iovec, and hence the source is incremented by the size of a non-compat iovec in the loop. This misses every other iovec in the source, and will run into garbage half way through the copies and return -EFAULT to the application. Maintain the source address separately and assign to our user vec pointer, so that copies always happen from the right source address. While in there, correct a bad placement of __user which triggered the following sparse warning prior to this fix: io_uring/rsrc.c:981:33: warning: cast removes address space '__user' of expression io_uring/rsrc.c:981:30: warning: incorrect type in assignment (different address spaces) io_uring/rsrc.c:981:30: expected struct iovec const [noderef] __user *uvec io_uring/rsrc.c:981:30: got struct iovec *[noderef] __user Fixes: f4eaf8ed ("io_uring/rsrc: Drop io_copy_iov in favor of iovec API") Reviewed-by: Gabriel Krisman Bertazi <krisman@suse.de> Signed-off-by: Jens Axboe <axboe@kernel.dk>

The runtime constant feature removes all the users of these variables, allowing the compiler to optimize them away. It's quite difficult to extract their values from the kernel text, and the memory saved by removing them is tiny, and it was never the point of this optimization. Since the dentry_hashtable is a core data structure, it's valuable for debugging tools to be able to read it easily. For instance, scripts built on drgn, like the dentrycache script[1], rely on it to be able to perform diagnostics on the contents of the dcache. Annotate it as used, so the compiler doesn't discard it.

Commit 8bccf667 ("Input: cypress_ps2 - report timeouts when reading command status") uncovered an existing problem with cypress_ps2 driver: it tries waiting on a PS/2 device waitqueue without using the rest of libps2. Unfortunately without it nobody signals wakeup for the waiting process, and each "extended" command was timing out. But the rest of the code simply did not notice it. Fix this by switching from homegrown way of sending request to get command response and reading it to standard ps2_command() which does the right thing.
