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.
