These two patches improve diskdump to support multiple dump devices.
Diskdump automatically tries to dump to another device when the troubles
like I/O error occur.
Multiple dump devices can be configured as follows. The dump devices
should be delimited by ":". The number of dump devices is unlimited.
# cat /etc/sysconfig/diskdump
In this cace, if the I/O error occurs on /dev/sdb6, diskdump tries to
dump to /dev/sdb5.
This patch is for kernel.
Apply the partial dump patch to the kernel beforehand.
