Subject: [PATCH 3/6] procfs: Use generic_file_llseek in /proc/kmsg
Date: Tue, 30 Mar 2010 08:20:12 +0200	[thread overview]
Message-ID: <1269930015-863-4-git-send-regression-fweisbec@gmail.com> (raw)
In-Reply-To: <1269930015-863-1-git-send-regression-fweisbec@gmail.com>

No need to hold the bkl to seek here, none of the other
fops callbacks use it.

Use generic_file_llseek explicitly.
