Merge branch 'for-linus' of git://git.kernel.dk/linux-2.6-block
* 'for-linus' of git://git.kernel.dk/linux-2.6-block:
block: fix setting of max_segment_size and seg_boundary mask
block: internal dequeue shouldn't start timer
block: set disk->node_id before it's being used
When block layer fails to map iov, it calls bio_unmap_user to undo
