[PATCHSET v2 cgroup/for-3.15] cgroup: drop module support and cgroup_root_mutex
Hello,
This is the second take. Changes from the last take[L] are
* Updated to reflect changes in fe1217c4f3f7 ("net: net_cls: move
cgroupfs classid handling into core").
* Rebased on top of the current linus#master + some cgroup fix
patches.
There's only one controller which makes use of the module support -
net_prio, which, non-coincidentally, isn't an actual resource
controller. It's highly unlikely that the actual resource controlling
controllers are gonna be made modular and we aren't gonna add more
non-resource controllers either, so the value of module support is
strictly restricted to the particular controller.
The controller is fairly simple while module support in cgroup core
adds quite a bit of complexity. Building the one controller as module
only saves less than half-page in vmlinux, which really can't justify
the additional complexity and (minute but existing) runtime overhead.
This patchset makes net_prio config options bool so that it can't be
built as modules and drops module support from cgroup core, which in
turn facilitates further simplification leading to removal of
cgroup_root_mutex by allowing iterating subsystems outside the
mutexes.
This patchset contains the following six patches.
0001-cgroup-make-CONFIG_CGROUP_NET_PRIO-bool-and-drop-unn.patch
0002-cgroup-drop-module-support.patch
0003-cgroup-clean-up-cgroup_subsys-names-and-initializati.patch
0004-cgroup-rename-cgroup_subsys-subsys_id-to-id.patch
0005-cgroup-update-locking-in-cgroup_show_options.patch
0006-cgroup-remove-cgroup_root_mutex.patch
0001-0002 drop cgroup module support.
0003-0004 are cleanups.
0005-0006 remove cgroup_root_mutex.
The patchset is on top of
linus#master 54c0a4b46150 ("Merge branch 'akpm' (incoming from Andrew)")
+ [1] [PATCHSET cgroup/for-3.14-fixes] cgroup: four misc fixes
