mm: Remove false WARN_ON from pagecache_isize_extended()
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. Signed-off-by: Jan Kara <jack@suse.cz> Reviewed-by: Dave Chinner <dchinner@redhat.com> Signed-off-by: Dave Chinner <david@fromorbit.com>
