Message-Id: <1452894065-29769-3-git-send-email-acme@kernel.org> Date: Fri, 15 Jan 2016 18:40:59 -0300 From: Arnaldo Carvalho de Melo <acme@...nel.org> To: Ingo Molnar <mingo@...nel.org> Cc: linux-kernel@...r.kernel.org, Ben Hutchings <ben@...adent.org.uk>, Peter Zijlstra <peterz@...radead.org>, Arnaldo Carvalho de Melo <acme@...hat.com> Subject: [PATCH 2/8] perf symbols: Fix reading of build-id from vDSO From: Ben Hutchings <ben@...adent.org.uk> We need to use the long name (the filename) when reading the build-id from a DSO. Using the short name doesn't work for (at least) vDSOs.
