Subject: api.c: Expose cgroup_test_subsys_mounted() to users of libcgroup.la
X-Git-Tag: v2.0.rc1~10^2~2
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=da36d96e95a34cfcfaad62ffc6ced6cf397f4555;p=thirdparty%2Flibcgroup.git

api.c: Expose cgroup_test_subsys_mounted() to users of libcgroup.la

Remove the static qualifier from cgroup_test_subsys_mounted().  As
part of the cgget refactor, cgget will utilize this function.
