This is v3 of blkcg_policy methods cleanup patchset. Changes from the
last take [L] are
* Rebased on top of block/for-linus.
* 0003-blkcg-remove-unnecessary-blkcg_root-handling-from-cs.patch and
0004-blkcg-restructure-blkg_policy_data-allocation-in-blk.patch
added. These are follow-up cleanups for the blkcg_policy_data
handling fixes which went into block/for-linus.
* 0010-blkcg-cosmetic-updates-about-blkcg_policy_data.patch and
0011-blkcg-replace-blkcg_policy-cpd_size-with-cpd_alloc-f.patch
added so that blkcg_policy_data handling is consistent with
blkg_policy_data handling.
This patchset contains assorted cleanups for blkcg_policy methods and
blk[c]g_policy_data handling.
* alloc/free added for blkg_policy_data. exit dropped.
* alloc/free added for blkcg_policy_data.
* blk-throttle's async percpu allocation is replaced with direct
allocation.
* all methods now take blk[c]g_policy_data instead of blkcg_gq or
blkcg.
