Subject: [RFC][PATCH 3/7] sched: Remove noop in lowest_flag_domain()
Date: Thu, 16 Jun 2011 21:55:19 -0400 [thread overview]
Message-ID: <20110617015918.505012497@goodmis.org> (raw)
In-Reply-To: 20110617015516.301117218@goodmis.org
[-- Attachment #1: 0003-sched-Remove-noop-in-lowest_flag_domain.patch --]
[-- Type: text/plain, Size: 795 bytes --]
From: Hillf Danton <dhillf@gmail.com>
Checking for the validity of sd is removed, since it is already
checked by the for_each_domain macro.
