[Gluster Build System (Code Review)] Change in glusterfs[master]: remove useless-if-before-free -- with-braces

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

    + kill %1
    Process leaked file descriptors. See http://wiki.jenkins-ci.org/display/JENKINS/Spawning+processes+from+build for more information
