Changes since v5/v6: - Move the sync_supers() to the global bdi_forker_task() thread, so we don't writeback the supers from all the bdi kupdated() tasks. - Make bdi_start_writeback() and bdi_writeback_all() be sync when called with WB_SYNC_ALL only. - Shuffle some more things around to make a cleaner series. The sync vs async nature of bdi_writeback_all() and bdi_start_writeback() isn't consistent through the series, but otherwise things should be sane. I'd appreciate if Richard and Yanmin could re-run testing with this, just to make sure that things are sane. For ease of patching, I've put the full diff here: http://kernel.dk/writeback-v7.patch and also stored this in a writeback-v7 branch that will not change, you can pull that into Linus tree from here: git://git.kernel.dk/linux-2.6-block.git writeback-v7 -- Jens Axboe
