X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=84c06566cfb84e5f6aed9582d4570df8406700c9;p=openwrt%2Fstaging%2Fblogic.git

selftests/ftrace: multiple_kprobes: Also check for support

The multiple_kprobes test case fails to check for KPROBE_EVENT support.
Add the check to prevent a false test result.
