Subject[GIT PULL] cgroup changes for v3.14-rc1
Hello, Linus.

The bulk of changes are cleanups and preparations for the upcoming
kernfs conversion.

* cgroup_event mechanism which is and will be used only by memcg is
moved to memcg.

* pidlist handling is updated so that it can be served by seq_file.
Also, the list is not sorted if sane_behavior. cgroup documentation
explicitly states that the file is not sorted but it has been for
quite some time.

* All cgroup file handling now happens on top of seq_file. This is to
prepare for kernfs conversion. In addition, all operations are
restructured so that they map 1-1 to kernfs operations.

* Other cleanups and low-pri fixes.

The following changes since commit 266ccd505e8acb98717819cef9d91d66c7b237cc:
