Re: [PATCH] bcache: fix writeback thread to sleep less intrusively

Hi :)

What's the state of this?

I have this issue on a number of EC2 instances that are using bcache
to speed up EBS access by caching on the ephemeral SSDs (writethrough
mode).

"echo 0 > /sys/block/bcache0/bcache/writeback_running" as suggested by
others stops the flood of "blocked" messages in dmesg, but it only
partly fixes the 2.0 minimum load average issue (instead, it's now a
1.0 minimum load average).

I just tried the latest kernel I could get my hands on for Ubuntu
Trusty, the mainline v3.15-rc2 (built April 20th), and it exhibits the
same behavior.

Thanks :)

Daniel
