| |
Hello, Linus.
This is cpuset changes for 3.9-rc1.
* Synchornization has seen a lot of changes with focus on decoupling cpuset synchronization from cgroup internal locking. After this change, there only remain a couple of mostly trivial dependencies on cgroup_lock outside cgroup core proper. cgroup_lock is scheduled to be unexported in this devel cycle. This will finally remove the fragile locking order around cgroup (cgroup locking wants to / should be one of the outermost but yet has been acquired from deep inside individual controllers).
* At this point, Li is most knowlegeable with cpuset and taking over the maintainership of cpuset.
This depends on cgroup_rightmost_descendant() implemented in cgroup/for-3.9 and this pull request assumes that cgroup/for-3.9 is already pulled in.
The changes are available in the git repository at:
