The reason why I put the 2 values in one sysfs file is that there is a similar
file 'vmcoreinfo' in sysfs.
# cat /sys/kernel/vmcoreinfo
1d75380 1000
Nothing wrong with two different files, I just wanted to export the vmcsinfo
with the interface that is the same as vmcoreinfo. So later in kexec-tools,
vmcsinfo note information will be handled in a very similar way as vmcoreinfo
note information.
