Merge tag 'v6.6-rc7.vfs.fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs
Pull vfs fix from Christian Brauner:
"An openat() call from io_uring triggering an audit call can apparently
cause the refcount of struct filename to be incremented from multiple
threads concurrently during async execution, triggering a refcount
underflow and hitting a BUG_ON(). That bug has been lurking around
since at least v5.16 apparently.
Switch to an atomic counter to fix that. The underflow check is
downgraded from a BUG_ON() to a WARN_ON_ONCE() but we could easily
remove that check altogether tbh"
