Subject: [PATCH 118/201] perf metric: Add events for the current list
mainline inclusion
from mainline-v5.9-rc1
commit fc393839c11bbe2c7f1a44ab34e5f2a219d8366e
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I8C0CX
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=fc393839c11bbe2c7f1a44ab34e5f2a219d8366e
----------------------------------------------------------------------
There's no need to iterate the whole list of groups, when adding new
events. The currently created groups are the ones we want to add.
