This is v2 of blkcg_policy methods cleanup patchset. 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.
