Subject: cgset: fix misleading error message
X-Git-Tag: v0.42.rc1~32
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=62f76650db84c0a25f76ece3a79d9d16a1e9f931;p=thirdparty%2Flibcgroup.git

cgset: fix misleading error message

When cgset fails to modify a cgroup, it output a
hardcoded error message which can cause user confusion.
This commit updates the error message to behave like
other error messages throughout libcgroup and produce
a more user-friendly output.
