File 82452a5d-libxl-rm-goto-libxlDomainShutdownThread.patch of Package libvirt.11701
commit 82452a5d7f55c7698459728a3ee071402f43bb4d Author: Jim Fehlig <jfehlig@suse.com> Date: Wed Oct 31 10:54:14 2018 -0600 libxl: Remove some goto labels in libxlDomainShutdownThread There are too many goto labels in libxlDomainShutdownThread. Convert the 'destroy' and 'restart' labels to helper functions, leaving only the commonly used pattern of 'endjob' and 'cleanup' labels.
