ext4: allow unlocked direct IO when pages are cached Currently we do not allow unlocked (meaning without inode_lock) direct IO when the file has any pages cached. This check is not needed anymore as we keep inode lock until ext4_direct_IO_write() and thus can happily writeback and evict any pages conflicting with current direct IO write.
