Andreas Gruenbacher 95ecbd0f16 Revert "gfs2: stop using generic_writepages in gfs2_ail1_start_one" ... Commit b2b0a5e978 switched from generic_writepages() to filemap_fdatawrite_wbc() in gfs2_ail1_start_one() on the path to replacing ->writepage() with ->writepages() and eventually eliminating the former. Function gfs2_ail1_start_one() is called from gfs2_log_flush(), our main function for flushing the filesystem log. Unfortunately, at least as implemented today, ->writepage() and ->writepages() are entirely different operations for journaled data inodes: while the former creates and submits transactions covering the data to be written, the latter flushes dirty buffers out to disk. With gfs2_ail1_start_one() now calling ->writepages(), we end up creating filesystem transactions while we are in the course of a log flush, which immediately deadlocks on the sdp->sd_log_flush_lock semaphore. Work around that by going back to how things used to work before commit b2b0a5e978 for now; figuring out a superior solution will take time we don't have available right now. However ... Since the removal of generic_writepages() is imminent, open-code it here. We're already inside a blk_start_plug() ... blk_finish_plug() section here, so skip that part of the original generic_writepages(). This reverts commit b2b0a5e978.
