If anyone has any objections, please let me know. ------------------ From: Jan Kara <jack@...e.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.
