Subject: [PATCH 00/17] md: cleanup on direct access to bvec table
Date: Thu, 16 Feb 2017 19:45:30 +0800 [thread overview]
Message-ID: <1487245547-24384-1-git-send-email-tom.leiming@gmail.com> (raw)
In MD's resync I/O path, there are lots of direct access to bio's
bvec table. This patchset kills most of them, and the conversion
is quite straightforward.
Once direct access to bvec table in MD is cleaned up, we may make
multipage bvec moving on.
Thanks,
Ming
