Subject: [PATCH 0/3] block: Per cpu merge stats and cfq fix
Date: Fri, 20 May 2011 20:02:44 -0400	[thread overview]
Message-ID: <1305936167-8932-1-git-send-email-vgoyal@redhat.com> (raw)

Hi Jens,

Here is the patch for making merge stats per cpu. While scanning the code
I also noticed that in one case I was not freeing up per cpu stats. First
patch fixes it. I also included Namhyung Kim's bio merge fix.

Thanks
Vivek
