Merge branch 'for-linus' of git://git.kernel.dk/linux-2.6-block
* 'for-linus' of git://git.kernel.dk/linux-2.6-block: cfq-iosched: cache prio_tree root in cfqq->p_root cfq-iosched: fix bug with aliased request and cooperation detection cfq-iosched: clear ->prio_trees[] on cfqd alloc block: fix intermittent dm timeout based oops umem: fix request_queue lock warning block: simplify I/O stat accounting pktcdvd.h should include mempool.h cfq-iosched: use the default seek distance when there aren't enough seek samples cfq-iosched: make seek_mean converge more quickly block: make blk_abort_queue() ignore non-request based devices block: include empty disks in /proc/diskstats bio: use bio_kmalloc() in copy/map functions bio: fix bio_kmalloc() block: fix queue bounce limit setting block: fix SG_IO vector request data length handling scatterlist: make sure sg_miter_next() doesn't return 0 sized mappings
