Subject: [PATCH 08/14] xfs: Convert to use invalidate_lock
Date: Tue, 15 Jun 2021 11:17:58 +0200	[thread overview]
Message-ID: <20210615091814.28626-8-jack@suse.cz> (raw)
In-Reply-To: <20210615090844.6045-1-jack@suse.cz>

Use invalidate_lock instead of XFS internal i_mmap_lock. The intended
purpose of invalidate_lock is exactly the same. Note that the locking in
__xfs_filemap_fault() slightly changes as filemap_fault() already takes
invalidate_lock.
