[PATCH] O(1) sys_exit(), threading, scalable-exit-2.5.31-B4
the attached patch updates a number of items:
- adds cleanups suggested by Christoph Hellwig: needed unlikely()
statements, a superfluous #define and line length problems.
- splits up the global ptrace list into per-task ptrace lists. This was
pretty straightforward, and this makes the worst-case exit() latency
O(nr_children).
the per-task ptrace lists unearthed a bug that the previous code did not
take care of: tasks on the ptrace list have to be correctly reparented as
well. This patch passed my stresstests as well.
