Subject: qemu_cgroup: initialize mem_mask to NULL
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=77a9dc0b8dc714212a8550314178b09684719546;p=people%2Fliuw%2Flibxenctrl-split%2Flibvirt.git

qemu_cgroup: initialize mem_mask to NULL

If 'virNumaGetHostNodeset()' fails then the error path will try to free
uninitialized pointer mem_mask. Introduced by commit af2a1f058.
