[Xen-devel] [PATCH] Show usage message of xm sysrq

[Masaki Kanno <kanno.masaki@xxxxxxxxxxxxxx>]

Hi,

Even if the "xm sysrq" command specified invalid arguments as 
below, the command error did not occur.

# xm sysrq vm1 m xyz
# 


If invalid arguments are specified, this patch shows an usage 
message.

# xm sysrq vm1 m xyz
Usage:  sysrq [DOM] [letter]

Sends a Linux sysrq to a domain.


 -h, --help
    Print this help.


Signed-off-by: Masaki Kanno <kanno.masaki@xxxxxxxxxxxxxx>

Best regards,
 Kan
