Date: Tue, 18 Oct 2011 18:44:45 -0600 From: David Ahern <dsahern@...il.com> To: acme@...stprotocols.net, mingo@...e.hu, linux-kernel@...r.kernel.org Cc: peterz@...radead.org, fweisbec@...il.com, David Ahern <dsahern@...il.com> Subject: [PATCH] perf tools: add prelink suggestion to dso update message Following a prelink run mapped files for long running processes can show as deleted. The current message suggests restarting long running processes. Add to that a suggestion that prelink might be the cause. Old message: /lib64/libc-2.14.so was updated, restart the long running apps that use it! New message: /lib64/libc-2.14.so was updated (is prelink enabled?). Restart the long running apps that use it!
