Subject: [GIT PULL] Block IO core bit for 3.2
Hi Linus,
This is the core bits pull request for 3.2. Executive summary:
- Some cleanups and refactoring of the __make_request() interface from
Christoph. We used to return 0/1 to control remap or queue behaviour,
but drivers often got that API wrong and used it for 0/-Exxx instead.
- Fix a bug in loop aops write handling.
- Two stable bug fixes for the block flush logic.
- A cleanup and fixup patchset from Tejun, attempting to really fix our
reference counting problems.
- Various little bug fixes, comments, cleansup.
Please pull!
