Subject: [patch 03/10] Kprobes - declare kprobe_mutex static
Date: Mon, 27 Aug 2007 11:56:04 -0400	[thread overview]
Message-ID: <20070827155850.932265049@polymtl.ca> (raw)
In-Reply-To: <20070827155601.360241608@polymtl.ca>

[-- Attachment #1: kprobes-declare-kprobes-mutex-static.patch --]
[-- Type: text/plain, Size: 1229 bytes --]

Since it will not be used by other kernel objects, it makes sense to declare it
static.
