Subject: [PATCH] selftests/bpf: Add powerpc support for get_preempt_count() in selftest
Date: Thu, 29 Jan 2026 11:10:35 +0530 [thread overview]
Message-ID: <20260129054035.168078-1-skb99@linux.ibm.com> (raw)
get_preempt_count() is enabled to return preempt_count for powerpc,
so that bpf_in_interrupt()/get_preempt_count() works for powerpc as
well.
