From f045b8c4b36baddcfbdd4d3d956446e688b0b3cd Mon Sep 17 00:00:00 2001 From: Krister Johansen Date: Wed, 5 Jul 2017 18:48:11 -0700 Subject: perf buildid-cache: Support binary objects from other namespaces Teach buildid-cache how to add, remove, and update binary objects from other mount namespaces. Allow probe events tracing binaries in different namespaces to add their objects to the probe and build-id caches too. As a handy side effect, this also lets us access SDT probes in binaries from alternate mount namespaces.
