[GIT PULL] core block bits for 2.6.38

From: Jens Axboe
Date: Thu Jan 13 2011 - 08:52:50 EST


Hi Linus,

Below are the core block bits for 2.6.38.

- Various optimizations and cleanups for CFQ from Gui and Shaohua

- Allow for hierarchical cgroups from Vivek.

- The in-kernel polling framework from Tejun. This means we can finally
get cdrom notifications correct.

The remainder is mostly little things here and there, cleanups and so on.
Apart from Tejuns works, there's nothing earth shattering in here.

Please pull.
