Subject: selftests/cgroup: Fix incorrect variable check in online_cpus()
X-Git-Url: http://git.ipfire.org/gitweb/index.cgi?a=commitdiff_plain;h=7ea04cc4fe3cee2139cc2474cadaecc7c53d986d;p=thirdparty%2Flinux.git

selftests/cgroup: Fix incorrect variable check in online_cpus()

"OFFLINE_CPUS" is a literal string that is always non-empty. It should
be "$OFFLINE_CPUS" to check the variable's value instead.
