Subject: perf mem: Introduce perf_mem_events__name function
X-Git-Tag: Ubuntu-5.10.0-12.13~13080^2~43^2~29
X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=2ba7ac5814a6952aad647ce31696b893772cbe83;p=mirror_ubuntu-hirsute-kernel.git

perf mem: Introduce perf_mem_events__name function

Wrap perf_mem_events[].name into perf_mem_events__name() so we could alter the
events name if needed.

This will be handy when changing latency settings for loads event in following
patch.
