Subject: [GIT PULL] Block drivers bits for 3.17-rc1
Hi Linus,
On top of the core pull request, here's the block driver pull request
for 3.17-rc1. Nothing out of the ordinary here, this pull request
contains:
- A big round of fixes for bcache from Kent Overstreet, Slava Pestov,
and Surbhi Palande. No new features, just a lot of fixes.
- The usual round of drbd updates from Andreas Gruenbacher, Lars
Ellenberg, and Philipp Reisner.
- virtio_blk was converted to blk-mq back in 3.13, but now Ming Lei has
taken it one step further and added support for actually using more
than one queue.
- Addition of an explicit SG_FLAG_Q_AT_HEAD for block/bsg, to compliment
the the default behavior of adding to the tail of the queue. From
Douglas Gilbert.
