From 2a03068c5cfa104768703cbefa2e23a6353f8de5 Mon Sep 17 00:00:00 2001 From: Adrian Hunter Date: Tue, 22 Jul 2014 16:17:53 +0300 Subject: [PATCH] perf tools: Pass machine to vdso__dso_findnew() This is preparation for removing the global variables used in vdso.c and thereby fixing the lifetime of the VDSO temporary file.
