From: Jiri Olsa Date: Wed, 3 Jun 2015 14:25:52 +0000 (+0200) Subject: perf stat: Replace transaction event possition check with id check X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=4c358d5cf36192f22b8d331779cb92e3ede9cddf;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git perf stat: Replace transaction event possition check with id check Using perf_stat::id to check for transaction events, instead of current position based way.
