Subject: [PATCHSET v3 block/for-4.3] blkcg: blkcg policy methods and data handling cleanup
Date: Sat, 11 Jul 2015 14:00:43 -0400 [thread overview]
Message-ID: <1436637654-28110-1-git-send-email-tj@kernel.org> (raw)
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.
This patchset contains the following 11 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-remove-unnecessary-blkcg_root-handling-from-cs.patch
0004-blkcg-restructure-blkg_policy_data-allocation-in-blk.patch
0005-blkcg-make-blkcg_activate_policy-allow-NULL-pd_init_.patch
0006-blkcg-replace-blkcg_policy-pd_size-with-pd_alloc-fre.patch
0007-blk-throttle-remove-asynchrnous-percpu-stats-allocat.patch
0008-blk-throttle-clean-up-blkg_policy_data-alloc-init-ex.patch
0009-blkcg-make-blkcg_policy-methods-take-a-pointer-to-bl.patch
0010-blkcg-cosmetic-updates-about-blkcg_policy_data.patch
0011-blkcg-replace-blkcg_policy-cpd_size-with-cpd_alloc-f.patch
0001-0005 are misc cleanups. 0006-0008 add alloc/free methods and
remove blk-throttle's async percpu allocation mechanism. 0009 makes
all methods take blkcg_policy_data. 0010-0011 apply similar cleanups
to blkcg_policy_data handling.
This patchset is also available in the following git branch.
git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup.git review-blkcg-methods-cleanup
and is on top of
block/for-linus 06b285bd1125 ("blkcg: fix blkcg_policy_data allocation bug")
+ [1] [PATCHSET block/for-4.3] writeback: cgroup writeback updates
+ [2] [PATCHSET v2 block/for-4.3] block, cgroup: make cfq charge async IOs to the appropriate blkcgs
diffstat follows, thanks.
