From: He Kuang Date: Thu, 19 May 2016 11:47:37 +0000 (+0000) Subject: perf tools: Set buildid dir under symfs when --symfs is provided X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a706670900073d236938d539d1109338d64b47bb;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git perf tools: Set buildid dir under symfs when --symfs is provided This patch moves the reference of buildid dir to 'symfs/.debug' and skips the local buildid dir when '--symfs' is given, so that every single file opened by perf is relative to symfs directory now.
