Hi Al, Jens, this is the third or fourth attempt. Al, would you please take a look at this? Would it be possible to get your ack and then merge this via Jens' tree? The patches attempt to optimize the periodic write-back and stop it when there are no dirty data. IOW, we do not want the thread to wake up every 5 seconds (by default), find there is nothing to do, and so on. We want to save power instead. The patches are against Jens Axboe's per-bdi write-back tree. Namely, against: git://git.kernel.dk/linux-2.6-block.git writeback-v12 Patches 01-16 introduce 2 VFS helpers and wrap all 'sb->s_dirt' manipulations. Patch 17 re-names s_dirt to s_dirty in order to make sure we catch all direct s_dirt accesses. Patch 18 optimizes the periodic 'sync_supers' thread. This used to be 'pdflush', but Jens re-worked this area and now it is called 'sync_supers'. By the way, with Jens' changes the former kupdated stuff stuff looks a lot cleaner and it is easier to work on top of that. -- Best Regards, Artem Bityutskiy (Ð?Ñ?Ñ?Ñ?м Ð?иÑ?Ñ?Ñ?кий) -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
