Run 'make oldconfig && make prepare' on kernel src to fix it. that diagnostic seems in... 18 Jun 2010 17:58

while_each_thread() under rcu_read_lock() is broken?
I think you're right. I can't see what would prevent that race. So for_each_process and do_each_thread are safe only under read_lock(&tasklist_lock) and while_each_thread is only safe under either that or siglock. (Also a few places using next_thread in similar loops outside those macros.) Perhaps we could... 9 Jul 2010 12:45
