[PATCH] cpuset semaphore depth check optimize
Optimize the deadlock avoidance check on the global cpuset
semaphore cpuset_sem. Instead of adding a depth counter to the
task struct of each task, rather just two words are enough, one
to store the depth and the other the current cpuset_sem holder.
Thanks to Nikita Danilov for the idea.

[ We may want to change this further, but at least it's now
a totally internal decision to the cpusets code ]
