From a73e24d240bc136619d382b1268f34d75c9d25ce Mon Sep 17 00:00:00 2001 From: Jiri Olsa Date: Thu, 15 Feb 2018 13:26:34 +0100 Subject: [PATCH] perf tools: Do not create kernel maps in sample__resolve() There's no need for kernel maps to be allocated at this point - sample processing. We search for kernel maps using the kernel map_groups in machine::kmaps which is static. If vmlinux maps for any reason still don't exist, the search correctly fails because they are not in the map group.
