In the Linux kernel, the following vulnerability has been resolved:
btrfs: unlock inode and extent in caller when io uring read extent fails
btrfs uring read extent() runs only after btrfs encoded read() has taken
the inode shared lock and the extent lock. On failure it used to unlock
in out fail, and a pages-array allocation failure returned -ENOMEM
without unlocking at all.
Unlock in the caller instead on all failure returns, matching the
copy to user() error path. The deferred -EIOCBQUEUED path still unlocks
in btrfs uring read finished().
