[GIT PULL] Core block IO bits for 3.15-rc
From: Jens Axboe
Date: Tue Apr 01 2014 - 15:05:26 EST
Hi Linus,
This is the pull request for the core block IO bits for the 3.15 kernel.
It's a smaller round this time, it contains:
- Various little blk-mq fixes and additions from Christoph and myself.
- Cleanup of the IPI usage from the block layer, and associated helper
code. From Frederic Weisbecker and Jan Kara.
- Duplicate code cleanup in bio-integrity from Gu Zheng. This will give
you a merge conflict, but that should be easy to resolve.
- blk-mq notify spinlock fix for RT from Mike Galbraith.
- A blktrace partial accounting bug fix from Roman Pen.
- Missing REQ_SYNC detection fix for blk-mq from Shaohua Li.
Please pull!
