[PATCH 0/3] introduce for_each_process_thread_{break,continue}() helpers

[Oleg Nesterov]

Hello,

IMHO this makes sense in any case, but mostly this is preparation for
another change: show_state_filter() should be preemptible. But this needs
more discussion, I'll write another email/patch when I fully understand
the hard-lockup caused by sysrq-t.

Oleg.
