Hello,
please consider backporting commit 08ef1af4de5f ("perf/core: Fix
unconditional security_locked_down() call") to stable kernels, as
without it SELinux requires an extraneous permission for
perf_event_open(2) calls with PERF_SAMPLE_REGS_INTR unset.
The range of target kernel versions is implied by the Fixes: tag.
Thanks,
