From: Namhyung Kim Date: Fri, 1 Aug 2014 05:59:31 +0000 (+0900) Subject: perf kmem: Do not ignore mmap events X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=64c40908938953d7afa90e9363327875286349e5;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git perf kmem: Do not ignore mmap events The perf kmem command didn't process mmap events for some unknown reason and it instead gets symbol info from a running kernel. This is problematic if perf kmem record was run on a different kernel. This patch adds the mmap event handlers and reverts the commit e727ca73f85d ("perf kmem: Resolve kernel symbols again").
