Merge branch 'for-3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup
Pull cgroup updates from Tejun Heo: - xattr support added. The implementation is shared with tmpfs. The usage is restricted and intended to be used to manage per-cgroup metadata by system software. tmpfs changes are routed through this branch with Hugh's permission. - cgroup subsystem ID handling simplified. * 'for-3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup: cgroup: Define CGROUP_SUBSYS_COUNT according the configuration cgroup: Assign subsystem IDs during compile time cgroup: Do not depend on a given order when populating the subsys array cgroup: Wrap subsystem selection macro cgroup: Remove CGROUP_BUILTIN_SUBSYS_COUNT cgroup: net_prio: Do not define task_netpioidx() when not selected cgroup: net_cls: Do not define task_cls_classid() when not selected cgroup: net_cls: Move sock_update_classid() declaration to cls_cgroup.h cgroup: trivial fixes for Documentation/cgroups/cgroups.txt xattr: mark variable as uninitialized to make both gcc and smatch happy fs: add missing documentation to simple_xattr functions cgroup: add documentation on extended attributes usage cgroup: rename subsys_bits to subsys_mask cgroup: add xattr support cgroup: revise how we re-populate root directory xattr: extract simple_xattr code from tmpfs
