From af6363374cbda5007e46efa99f7346efd4eea5fc Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Sat, 8 Feb 2014 10:36:58 -0500 Subject: cgroup: make CONFIG_CGROUP_NET_PRIO bool and drop unnecessary init_netclassid_cgroup() net_prio is the only cgroup which is allowed to be built as a module. The savings from allowing one controller to be built as a module are tiny especially given that cgroup module support itself adds quite a bit of complexity. Given that none of other controllers has much chance of being made a module and that we're unlikely to add new modular controllers, the added complexity is simply not justifiable. As a first step to drop cgroup module support, this patch changes the config option to bool from tristate and drops module related code from it. Also, while an earlier commit fe1217c4f3f7 ("net: net_cls: move cgroupfs classid handling into core") dropped module support from net_cls cgroup, it retained a call to cgroup_load_subsys(), which is noop for built-in controllers. Drop it along with init_netclassid_cgroup(). v2: Removed modular version of task_netprioidx() in include/net/netprio_cgroup.h as suggested by Li Zefan. v3: Rebased on top of fe1217c4f3f7 ("net: net_cls: move cgroupfs classid handling into core"). net_cls cgroup part is mostly dropped except for removal of init_netclassid_cgroup().
