Hello, This is repost of the following. http://thread.gmane.org/gmane.linux.kernel.cgroups/8981 It got reviewed and acked then but I somehow forgot apply and Vladimir reporting the same bug that the first patch in the original patch fixed reminded me. The first patch is already applied to cgroup/for-3.13-fixes which is pulled into for-3.14 for this series. While the patches are not completely identical, the adjustments are trivial. css_id got ripped out in the meantime, so "[PATCH 4/9] cgroup: move css_id commit from cgroup_populate_dir() to online_css()" is dropped and the patches are refreshed to reflect the dropping of css_id handling in cgroup_create(). I'm applying the series to cgroup/for-3.14. The original patchset description follows. Thanks and sorry about the messup. For unified hierarchy, a css's (cgroup_subsys_state) lifetime will be different from that of the associated cgroup. css's may be created and destroyed dynamically over the lifetime of a single cgroup. The previous changes decoupled css destruction from cgroup's. This patchset decouples css creation from cgroup's. This patchset contains the following seven patches. 0001-cgroup-css-iterations-and-css_from_dir-are-safe-unde.patch 0002-cgroup-make-for_each_subsys-useable-under-cgroup_roo.patch 0003-cgroup-reorder-operations-in-cgroup_create.patch 0004-cgroup-combine-css-handling-loops-in-cgroup_create.patch 0005-cgroup-factor-out-cgroup_subsys_state-creation-into-.patch 0006-cgroup-implement-for_each_css.patch 0007-cgroup-remove-for_each_root_subsys.patch 0001-0002 are prep patches. 0003-0005 collect css creation operations into single loop and factor it out into create_css(). 0006-0007 are somewhat tangential. As everything is css based now and the enabled set of css's might be differ depending on the specific cgroup in the future, they introduce for_each_css() and replace most uses of for_each_root_subsys() with it. The two left overs are opencoded and for_each_root_subsys() and the related logic are removed. This patchset shouldn't bring any userland noticeable behavior changes. It's on top of cgroup/for-3.12 d1625964da ("cgroup: fix cgroup_css() invocation in css_from_id()") and available in the following git branch. include/linux/cgroup.h | 9 - kernel/cgroup.c | 300 ++++++++++++++++++++++++++----------------------- 2 files changed, 161 insertions(+), 148 deletions(-) -- tejun -- To unsubscribe from this list: send the line "unsubscribe cgroups" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
