[Crash-utility] [PATCH] Add a new option -r to cgget

Hello Dave, This patch allows cgget to display one or some parameters of a controller of cgroup and fix some bugs. One will find it more efficient when he just focus on some parameters instead of the whole controller. Here are examples: 1. crash> cgget -r cpuset.mems / /: cpuset.mems: 0 2. crash> cgget -r memory.usage / /: memory.memsw.max_usage_in_bytes: 0 memory.memsw.usage_in_bytes: 1368694784 memory.max_usage_in_bytes: 0 memory.usage_in_bytes: 1368694784 To apply this patch, enter to crash-<version> directory and run the commands as follows: $ cp cgget.pacth ./ $ patch -p0 -i cgget.patch For more information, please refer to the attachment. Thanks. -- Zhang Xiaohe Regards -------------------------------------------------- Development Dept.I Nanjing Fujitsu Nanda Software Tech.
