I'd like to encourage including the patch:
Cpuset: fix ABBA deadlock with cpu hotplug lock
in 2.6.18-rc2-mmx. This patch was sent to lkml, copied to akpm, 14 July. It was sent again to lkml, in response to a request for a copy from Linus, on 23 July, copied again to akpm.
Granted, the case for including it is not absolute.
The fix is simple enough and fixes a definite deadlock, as verified by testing results on the system that was seeing this deadlock.
However ... only one system, world-wide, has the magic workload to provoke this deadlock, so far. And it involves the cpu hotplug lock, which perhaps Linus would like to nuke entirely.
