From 4996976fcde4bb738ce68ca01a8b358d71aab7bb Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Wed, 31 May 2017 20:40:15 +1000 Subject: [PATCH] selftests: sync: Skip the test if kernel support is not found The "Sync framework" test doesn't work if the kernel has no support, obviously. Rather than reporting a failure, check for the kernel support by looking for /sys/kernel/debug/sync/sw_sync, and if not found skip the test.
