    cgroup: remove struct cgroup_scanner · e535837b
    Tejun Heo 提交于
    cgroup_scan_tasks() takes a pointer to struct cgroup_scanner as its
    sole argument and the only function of that struct is packing the
    arguments of the function call which are consisted of five fields.
    It's not too unusual to pack parameters into a struct when the number
    of arguments gets excessive or the whole set needs to be passed around
    a lot, but neither holds here making it just weird.
    
    Drop struct cgroup_scanner and pass the params directly to
    cgroup_scan_tasks().  Note that struct cpuset_change_nodemask_arg was
    added to cpuset.c to pass both ->cs and ->newmems pointer to
    cpuset_change_nodemask() using single data pointer.
    
    This doesn't make any functional differences.
