writeback tree status (for 3.2 merge window)
Subsystems (2)
Hi,
There are 3 patchsets sitting in the writeback tree.
1) IO-less dirty throttling v12
https://github.com/fengguang/linux/commits/dirty-throttling-v12
2) writeback reasons tracing from Curt Wohlgemuth
https://github.com/fengguang/linux/commits/writeback-reason
3) writeback queuing changes from Jan Kara and me
https://github.com/fengguang/linux/commits/requeue-io-wait
They have been merged into this branch testing in linux-next for a while:
https://github.com/fengguang/linux/commits/writeback-for-next
Since (3) still has an unresolved issue (detailed in the below links), it looks better to hold it back for this merge window.
http://permalink.gmane.org/gmane.linux.kernel/1206315
http://permalink.gmane.org/gmane.linux.kernel/1206316
The patches from (1,2) together with 2 tracing patches essential for debugging (1) have been pushed to the "writeback-for-linus" branch:
http://git.kernel.org/?p=linux/kernel/git/wfg/linux.git;a=shortlog;h=refs/heads/writeback-for-linus
If no objections, I'll send a pull request to Linus soon.
Thanks,
Fengguang

Given that we have run into issues so much with it that's proably the better idea.
To fix the originally reported issue with the missing file size updates in XFS we plan to simply log all filesize changes in XFS. Currently I had this in the 3.3 queue, but in the worst case we might have to move this forward to 3.2.

Please do so. I'm really looking forward to see the I/O-less balance_dirty_pages in ASAP.

OK. Anyway I'll report any progress early on (3).
