Subject: [PATCH 1/1] Fix Compilation Warning in kernel/trace/trace.c
Date: Fri, 16 Dec 2011 02:15:24 -0500	[thread overview]
Message-ID: <1324019724-3422-1-git-send-email-devendra.aaru@gmail.com> (raw)

there was a compilation warning saying
kernel/trace/trace.c:3644:8: warning: ‘page2’ may be used uninitialized in this function

The page2 pointer is used only when nr_pages = 2.

Assigned a null value to the page2 to get rid of warning.
