Hello, This became a rather large patchset mostly because there are a lot of weirdities and subtle breakages in create/destroy/load/unload paths. The goal of the patchset is allowing ->post_create() to fail and renaming ->create/post_create/pre_destroy/destroy() to ->css_alloc/css_online/css_offline/css_free(). This patchset contains the following seventeen patches. 0001-cgroup-remove-incorrect-dget-dput-pair-in-cgroup_cre.patch 0002-cgroup-initialize-cgrp-allcg_node-in-init_cgroup_hou.patch 0003-cgroup-open-code-cgroup_create_dir.patch 0004-cgroup-create-directory-before-linking-while-creatin.patch 0005-cgroup-cgroup-dentry-isn-t-a-RCU-pointer.patch 0006-cgroup-remove-duplicate-RCU-free-on-struct-cgroup.patch 0007-cgroup-make-CSS_-flags-bit-masks-instead-of-bit-posi.patch 0008-cgroup-trivial-cleanup-for-cgroup_init-load_subsys.patch 0009-cgroup-lock-cgroup_mutex-in-cgroup_init_subsys.patch 0010-cgroup-fix-harmless-bugs-in-cgroup_load_subsys-fail-.patch 0011-cgroup-separate-out-cgroup_destroy_locked.patch 0012-cgroup-introduce-CSS_ONLINE-flag-and-on-offline_css-.patch 0013-cgroup-simplify-cgroup_load_subsys-failure-path.patch 0014-cgroup-use-mutex_trylock-when-grabbing-i_mutex-of-a-.patch 0015-cgroup-update-cgroup_create-failure-path.patch 0016-cgroup-allow-post_create-to-fail.patch 0017-cgroup-rename-create-post_create-pre_destroy-destroy.patch 0001 is a bugfix. Tagged for -stable. I don't I'll push it through for-3.7-fixes tho. This has been broken forever and nobody reported anything yet. 0002-0011 are various fixes and cleanups to prepare for the following changes. Each should be self-explanatory. 0012-0015 are preparation patches more directly related to allowing failure of ->post_create(). 0016 allows ->post_create() to fail. 0017 renames ops and updates documentation. This patchst is on top of cgroup/for-3.8 and available on the following git branch. git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup.git review-cgroup-online-may-fail and contains the following changes.
