Subject: [PATCH] allow oom_adj of saintly processes
Date: Sun, 18 Feb 2007 15:13:36 +0530 [thread overview]
Message-ID: <20070218094336.GM11084@always.joy.eth.net> (raw)
If the badness of a process is zero then oom_adj>0 has no effect. This
patch makes sure that the oom_adj shift actually increases badness
points appropriately.
I am not subscribed. Please CC me with any comments. Thanks.
