Subject: [PATCH 23/33] perf kmem: Do not ignore mmap events
Date: Mon,  4 Aug 2014 13:17:34 -0300	[thread overview]
Message-ID: <1407169064-25625-24-git-send-email-acme@kernel.org> (raw)
In-Reply-To: <1407169064-25625-1-git-send-email-acme@kernel.org>

From: Namhyung Kim <namhyung@kernel.org>

The perf kmem command didn't process mmap events for some unknown reason
and it instead gets symbol info from a running kernel.  This is
problematic if perf kmem record was run on a different kernel.

This patch adds the mmap event handlers and reverts the commit
e727ca73f85d ("perf kmem: Resolve kernel symbols again").
