Message-ID: <lsq.1369712993.492145735@decadent.org.uk> Date: Tue, 28 May 2013 04:49:53 +0100 From: Ben Hutchings <ben@...adent.org.uk> To: linux-kernel@...r.kernel.org, stable@...r.kernel.org CC: akpm@...ux-foundation.org, "David S. Miller" <davem@...emloft.net> Subject: [57/94] perf: net_dropmonitor: Fix symbol-relative addresses 3.2.46-rc1 review patch. If anyone has any objections, please let me know. ------------------ From: Ben Hutchings <ben@...adent.org.uk> commit 5a1e99dd2028e00998d42029be86835d8ef4a46e upstream. The comparison between traced and symbol addresses is backwards: if the traced address doesn't exactly match a symbol (which we don't expect it to), we'll show the next symbol and the offset to it, whereas we should show the previous symbol and the offset from it.
