Merge branch 'for-2.6.29' of git://git.kernel.dk/linux-2.6-block
* 'for-2.6.29' of git://git.kernel.dk/linux-2.6-block: (43 commits) bio: get rid of bio_vec clearing bounce: don't rely on a zeroed bio_vec list cciss: simplify parameters to deregister_disk function cfq-iosched: fix race between exiting queue and exiting task loop: Do not call loop_unplug for not configured loop device. loop: Flush possible running bios when loop device is released. alpha: remove dead BIO_VMERGE_BOUNDARY Get rid of CONFIG_LSF block: make blk_softirq_init() static block: use min_not_zero in blk_queue_stack_limits block: add one-hit cache for disk partition lookup cfq-iosched: remove limit of dispatch depth of max 4 times quantum nbd: tell the block layer that it is not a rotational device block: get rid of elevator_t typedef aio: make the lookup_ioctx() lockless bio: add support for inlining a number of bio_vecs inside the bio bio: allow individual slabs in the bio_set bio: move the slab pointer inside the bio_set bio: only mempool back the largest bio_vec slab cache block: don't use plugging on SSD devices ...
