[git pull] drm fixes
Okay so while I admire the regression and oops only line, it sorta of messes up new features that went in -rc1 that need tweaking now that people are testing them.

Now with 2.6.35-rc1, we could hit it often with a test case fio_aio_randwrite_4k. We test it by a JBOD with 12 disks. Every disk has 2 partitions. Ev... 8 Jun 2010 22:48
