Re: [PATCH] xencommons: modprobe xenfs if it not be loaded

[Yu Zhiguo <yuzg@cn.fujitsu.com>]

Do a small fix in order to be compatible with the old Dom0 kernel
which has no xenfs.ko.

-----------

If xenfs is compiled as a module, now cannot complete
'service xencommons start', modprobe xenfs can fix it.
