[Crash-utility] [Crash] [PATCH] add a new command: lscgroup

Hello Dave, I have been working on a new command named lscgroup to list cgroups' information and finished it recently. This command displays all the cgroups' information or the appointed cgroups' information relatively according to user's input. The following shows the two types of output. 1.Display all the cgroups' information of the system. crash>lscgroup blkio:/ blkio:/libvirt blkio:/libvirt/lxc blkio:/libvirt/qemu net_cls:/ ... ... cpuset:/ cpuset:/libvirt cpuset:/libvirt/lxc cpuset:/libvirt/qemu 2.Display the appointed cgroups' information. crash> lscgroup memory:/ cpuset:/libvirt memory:/ memory:/libvirt memory:/libvirt/lxc memory:/libvirt/qemu cpuset:/libvirt cpuset:/libvirt/lxc cpuset:/libvirt/qemu To see more details, please refer to the help information and the patch. To build the module from the top-level crash-<version> directory, enter: $ cp <path-to>/lscgroup.c extensions $ make extensions
