Message-Id: <1455604661-9357-1-git-send-email-eranian@google.com> Date: Tue, 16 Feb 2016 07:37:41 +0100 From: Stephane Eranian <eranian@...gle.com> To: linux-kernel@...r.kernel.org Cc: acme@...hat.com, peterz@...radead.org, mingo@...e.hu, ak@...ux.intel.com, kan.liang@...el.com, jolsa@...hat.com, namhyung@...nel.org, adrian.hunter@...el.com, dsahern@...il.com Subject: [PATCH] perf/jvmti: add check for java alternatives cmd in Makefile This patch modifies the jvmti makefile to check if /usr/sbin/java-update-alternatives is present. If so, then use it, if not then use the altenatives command. This helps handle the difference between Ubuntu and Fedora Linux distributions.
