+Subject: mm: Remove false WARN_ON from pagecache_isize_extended()
+
+From: Jan Kara <jack@suse.cz>
+
+commit f55fefd1a5a339b1bd08c120b93312d6eb64a9fb upstream.
+
+The WARN_ON checking whether i_mutex is held in
+pagecache_isize_extended() was wrong because some filesystems (e.g.
+XFS) use different locks for serialization of truncates / writes. So
+just remove the check.
