Subject: [PATCH] make refrigerator cold
Date: Mon, 21 Sep 2009 21:04:16 -0700 [thread overview]
Message-ID: <20090921210416.1982bcab@nehalam> (raw)
By marking it cold, then the code path in kernel thread
usage of try_to_freeze() that is normally used be
selected.
Don't think it matters that much for performance but the
concordance of this patch struck me as humorous.
