selftests/bpf: test_stacktrace_build_id: use kprobe/urandom_read

Yauheni Kaliuta · Yauheni Kaliuta · commit 472f00f1ad74 · 2023-01-18T16:25:10.000+02:00
Upstream status: RHEL-only Bugzilla: https://bugzilla.redhat.com/2161467 The test uses kprobe/urandom_read_iter which has not been ported to RHEL9 yet (drivers/char/urandom.c). There is no difference for the test which probe to use to check backtrace, so use existing urandom_read. Signed-off-by: Yauheni Kaliuta <ykaliuta@redhat.com>
