Subject: [PATCHSET cgroup/for-4.3] cgroup,memcg: generalize event handling and enable notifications on "memory.events"

Hello,

This patchset establishes conventions on low frequency events,
converts "cgroup.populated" to "cgroup.events" accordingly,
generalizes event handling and enable notifications for
"memory.events".

This patchset contains the following eight patches.

 0001-cgroup-replace-cgroup.populated-with-cgroup.events.patch
 0002-cgroup-replace-cftype-mode-with-CFTYPE_WORLD_WRITABL.patch
 0003-cgroup-relocate-cgroup_populate_dir.patch
 0004-cgroup-make-cgroup_addrm_files-clean-up-after-itself.patch
 0005-cgroup-cosmetic-updates-to-rebind_subsystems.patch
 0006-cgroup-restructure-file-creation-removal-handling.patch
 0007-cgroup-generalize-obtaining-the-handles-of-and-notif.patch
 0008-memcg-generate-file-modified-notifications-on-memory.patch

0001 replaces "cgroup.populated" with "cgroup.events".  0002-0006 are
prep patches.  0007 generalizes event notification.  0008 hook up
event notifications for "memory.events".

This patchset is on top of cgroup/for-4.3 e753531991b8 ("Merge branch
'for-4.3-unified-base' into for-4.3") and available in the following
git branch.
