** Description changed:
+ ==================
+ SRU Justification
+ 1. Impact: libvirt over time consumes excessive memory due to a call to
libnetcf
+ 2. Development fix: a patch to free a path which was being leaked
+ 3. Stable fix: same as development fix
+ 4. Test case: start libvirtd, and connect to it with virt-manager. Leave
that running. Run top in a terminal, hit 'M' to sort by memory, and watch for
RSS for libvirtd to grow. Give it an hour or two to grow by a few M.
+ 5. Regression potential: there should be none as this only causes a path to
be freed (after an earlier check for failure which should ensure the path is in
fact allocated).
+ ==================
libvirtd is using excessive amounts of memory after a week or so of uptime:
