From a89e5abe3efcc7facc666d3985769278937f86b0 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Thu, 7 Jan 2010 19:59:39 -0200 Subject: perf symbols: Record the domain of DSOs in HEADER_BUILD_ID header table MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit So that we can restore them to the right DSO list (either dsos__kernel or dsos__user). We do that just like the kernel does for the other events, encoding PERF_RECORD_MISC_{KERNEL,USER} in perf_event_header.
