[libvirt] [PATCH 1/8] cgroup: use consistent formatting
Eric Blake
eblake at redhat.com
Mon Aug 12 23:27:51 UTC 2013
Format all functions with two blank lines between, and return type
on separate line from function name. Also break some lines longer
than 80 columns. This makes the subsequent macro refactoring
less noisy.
* src/util/vircgroup.c: Match prevailing style.
