From 868a832918f621b7576655c00067f20326ef3931 Mon Sep 17 00:00:00 2001 From: Krister Johansen Date: Wed, 5 Jul 2017 18:48:12 -0700 Subject: perf top: Support lookup of symbols in other mount namespaces. The perf top command needs to unshare its fs from the helper threads in order to successfully setns(2) during its symbol lookup. It also needs to impelement a force flag to ignore ownership of perf-.map files.
