    Merge branch 'for-4.2' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup · bbe179f8
    Linus Torvalds 提交于
    Pull cgroup updates from Tejun Heo:
    
     - threadgroup_lock got reorganized so that its users can pick the
       actual locking mechanism to use.  Its only user - cgroups - is
       updated to use a percpu_rwsem instead of per-process rwsem.
    
       This makes things a bit lighter on hot paths and allows cgroups to
       perform and fail multi-task (a process) migrations atomically.
       Multi-task migrations are used in several places including the
       unified hierarchy.
    
     - Delegation rule and documentation added to unified hierarchy.  This
       will likely be the last interface update from the cgroup core side
       for unified hierarchy before lifting the devel mask.
    
     - Some groundwork for the pids controller which is scheduled to be
       merged in the coming devel cycle.
