Subject: perf util: Skip reading header_event file
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2b2efc7fb8a3ede936580e870c5f809e491c925c;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

perf util: Skip reading header_event file

It seems perf does not parse header_event file so we can skip it as we
do for header_page file.
