Subject: cgroup-util: make definition of CGROUP_CONTROLLER_TO_MASK() unsigned
X-Git-Tag: v240~458^2
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=46f84f955fa718fe674bc56e7ea40cc286043142;p=thirdparty%2Fsystemd.git

cgroup-util: make definition of CGROUP_CONTROLLER_TO_MASK() unsigned

Otherwise doing comparing a CGroupMask (which is unsigned in effect)
with the result of CGROUP_CONTROLLER_TO_MASK() will result in warnings
about signedness differences.
