Subject: selftests/cgroup: Fix string comparison in write_test
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=2a3d7256faf06d1a15bb5b07e851ac4e1680c26d;p=thirdparty%2Fkernel%2Flinux.git

selftests/cgroup: Fix string comparison in write_test

Use string comparison (!=) instead of numeric comparison (-ne) for
cpuset values like "0-1".
For example:
$ [[ "0-1" != "2-3" ]] && echo "true" || echo "false"
true
$ [[ "0-1" -ne "2-3" ]] && echo "true" || echo "false"
false
