Subject: perf_counter: Rename enums
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1c432d899d32d36371ee4ee310fa3609cf0e5742;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

perf_counter: Rename enums

Rename the perf enums to be in the 'perf_' namespace and strictly
enumerate the ABI bits.
