Subject: [PATCH 0/3] introduce for_each_process_thread_{break,continue}() helpers
Date: Mon, 25 Jul 2016 18:23:32 +0200 [thread overview]
Message-ID: <20160725162332.GA23935@redhat.com> (raw)
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.
