Merge branch 'for-2.6.33' of git://git.kernel.dk/linux-2.6-block
* 'for-2.6.33' of git://git.kernel.dk/linux-2.6-block: (113 commits) cfq-iosched: Do not access cfqq after freeing it block: include linux/err.h to use ERR_PTR cfq-iosched: use call_rcu() instead of doing grace period stall on queue exit blkio: Allow CFQ group IO scheduling even when CFQ is a module blkio: Implement dynamic io controlling policy registration blkio: Export some symbols from blkio as its user CFQ can be a module block: Fix io_context leak after failure of clone with CLONE_IO block: Fix io_context leak after clone with CLONE_IO cfq-iosched: make nonrot check logic consistent io controller: quick fix for blk-cgroup and modular CFQ cfq-iosched: move IO controller declerations to a header file cfq-iosched: fix compile problem with !CONFIG_CGROUP blkio: Documentation blkio: Wait on sync-noidle queue even if rq_noidle = 1 blkio: Implement group_isolation tunable blkio: Determine async workload length based on total number of queues blkio: Wait for cfq queue to get backlogged if group is empty blkio: Propagate cgroup weight updation to cfq groups blkio: Drop the reference to queue once the task changes cgroup blkio: Provide some isolation between groups ...
