Cluster service failure when "rgmanager_t" type executed sigkill action on type unconfined_t in RHEL 6

Issue

• If a filesystem resource in Cluster is configured with "force_unmount=1", fuser is used for sending sigkill to processes in order to force an unmount. SELinux is preventing this from happening. Logs shows the following:

    Jan 25 10:36:16 test01 setroubleshoot: SELinux is preventing /sbin/fuser "sigkill" access . For complete SELinux messages. run sealert -l 5e12cb2b-c359-4411-9f06-bca39353cef7
  

•   Audit.log shows the following:
