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
