Pending FSes (no one picked them) are: 1. ext4 - Ted is still being busy. 2. sysv, ufs - I hope you'd pick After this we will be able to kill sync_supers() completely and get rid of another source of regular wake-ups in the kernel. And interestingly, it will be the final end of pdflush - at old times it woke up periodically and flushed everything (forked itself as well). Then Jens cut off the data write-back part and put it to per-block device bdi threads. They originally also waked-up every 5 seconds, but I fixed this in v2.6.36 (6467716) and they stopped misbehaving. Jens transformed the superblock write-out part of pdflush 'sync_supers()', and I could not kill it because I did not have enough time and Al's request to change all users sounded unrealistic to me. But now I hope to actually finish this. -- Best Regards, Artem Bityutskiy
