Subject: [PATCHSET cgroup/for-3.15] cgroup: more cleanups

Hello,

This series contains assorted cleanups which also prepare for the
planned migration taskset handling update.

This patchset contains the following sixteen patches.

 0001-cgroup-disallow-xattr-release_agent-and-name-if-sane.patch
 0002-cgroup-drop-CGRP_ROOT_SUBSYS_BOUND.patch
 0003-cgroup-enable-task_cg_lists-on-the-first-cgroup-moun.patch
 0004-cgroup-relocate-cgroup_enable_task_cg_lists.patch
 0005-cgroup-implement-cgroup_has_tasks-and-unexport-cgrou.patch
 0006-cgroup-reimplement-cgroup_transfer_tasks-without-usi.patch
 0007-cgroup-make-css_set_lock-a-rwsem-and-rename-it-to-cs.patch
 0008-cpuset-use-css_task_iter_start-next-end-instead-of-c.patch
 0009-cgroup-remove-css_scan_tasks.patch
 0010-cgroup-separate-out-put_css_set_locked-and-remove-pu.patch
 0011-cgroup-move-css_set_rwsem-locking-outside-of-cgroup_.patch
 0012-cgroup-drop-skip_css-from-cgroup_taskset_for_each.patch
 0013-cpuset-don-t-use-cgroup_taskset_cur_css.patch
 0014-cgroup-remove-cgroup_taskset_cur_css-and-cgroup_task.patch
 0015-cgroup-cosmetic-updates-to-cgroup_attach_task.patch
 0016-cgroup-unexport-functions.patch

The notables ones are

 0003-0004 move task_cg_list enabling to the first mount instead of
 the first css task iteration.

 0005-0009 make css_set_lock a rwsem so that css_task_iter allows
 blocking during iteration and removes css_scan_tasks().

 0010-0015 clean up migration path to prepare for the planned
 migration taskset handling update.
