Subject: [PATCH] xfs: use invalidate_lock to check the state of mmap_lock
Git-commit: 82af88063961da9425924d9aec3fb67a4ebade3e
Patch-mainline: v5.19-rc5
References: git-fixes
We should use invalidate_lock and XFS_MMAPLOCK_SHARED to check the state
of mmap_lock rw_semaphore in xfs_isilocked(), rather than i_rwsem and
XFS_IOLOCK_SHARED.
Fixes: 2433480a7e1d ("xfs: Convert to use invalidate_lock")
