From c25ec42f846f702f8f532fbc890171e3a1f6ec85 Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Thu, 8 Jun 2017 16:31:08 +0900 Subject: [PATCH] perf symbols: Keep DSO->symtab_type after decompress The symsrc__init() overwrites dso->symtab_type as symsrc->type in dso__load_sym(). But for compressed kernel modules in the build-id cache, it should have original symtab type to be decompressed as needed. This fixes perf annotate to show disassembly of the function properly.
