Subject: [GIT PULL] core block bits for 2.6.37-rc1
Hi Linus,
This first pull request is the core bits, meaning general
block layer changes or core support. Should be clean this time,
only 'weird bit' is the seemingly duplicate entry from Malahal.
This is caused by the first patch being buggy (and later
reverted), second patch used the same single line description.
Nothing really exciting in here. A good collection of fixes, some of
which are marked for stable as well.
The biggest addition this time around is the block IO throttling support
from Vivek.
Please pull.
