Subject: [patch v1 06/12] IPVS: ip_vs_{un,}bind_scheduler NULL arguments
Date: Sun, 22 Aug 2010 21:45:03 +0900 [thread overview]
Message-ID: <20100822124858.738725404@vergenet.net> (raw)
In-Reply-To: 20100822124457.339517323@vergenet.net
[-- Attachment #1: ip_vs_bind_scheduler-null.patch --]
[-- Type: text/plain, Size: 1918 bytes --]
In general NULL arguments aren't passed by the few callers that exist,
so don't test for them.
The exception is to make passing NULL to ip_vs_unbind_scheduler() a noop.
