[stable] Please apply 037a3c43edfb: perf/core: Detach event groups during remove_on_exec

[Taeyang Lee]

Hi Linux kernel stable team,

Please apply the following upstream commit to the supported stable trees:

037a3c43edfb597665dd34457cd22b14692f2ba3
("perf/core: Detach event groups during remove_on_exec")

This fixes inconsistent perf event group state during remove_on_exec,
which can corrupt the PMU context active list.

I checked that the upstream commit cherry-picks cleanly onto the following
stable branches:

linux-7.1.y
linux-6.18.y

For older supported branches, I sent adjusted backports separately.

Thanks,
