Changes from the last take [L] are * Rebased on top of v4.2-rc1 and other pending patches. v4.2-rc1 added a patch to add per-blkcg policy data which is allocated by blkcg core as per-blkcg_gq policy data was before this patchset making the two inconsistent. I'll follow up with per-blkcg policy data update. This patchset contains assorted cleanups for blkcg_policy methods. * alloc/free are added. exit is dropped. * blk-throttle's async percpu allocation is replaced with direct allocation. * all methods now take blkcg_policy_data instead of blkcg_gq. Nothing too controversial. Jens, as we're at the beginning of the 4.2 merge window, I'll ping / repost this patchset along with other pending patchsets once -rc1 drops. This patchset contains the following seven patches. 0001-blkcg-remove-unnecessary-request_list-blkg-NULL-test.patch 0002-blkcg-use-blkg_free-in-blkcg_init_queue-failure-path.patch 0003-blkcg-make-blkcg_activate_policy-allow-NULL-pd_init_.patch 0004-blkcg-replace-blkcg_policy-pd_size-with-pd_alloc-fre.patch 0005-blk-throttle-remove-asynchrnous-percpu-stats-allocat.patch 0006-blk-throttle-clean-up-blkg_policy_data-alloc-init-ex.patch 0007-blkcg-make-blkcg_policy-methods-take-a-pointer-to-bl.patch 0001-0003 are misc cleanups. 0004-0006 add alloc/free methods and remove blk-throttle's async percpu allocation mechanism. 0007 makes all methods take blkcg_policy_data.
