Patch 19:      Export kexec_in_progress for modules

Isn't there another way to differentiate kexec reboot?

There's that "kexec reboot" string passed as the cmd to the reboot
notifier.
Maybe we can make it somehow more well defined API and use it?

A string? Dear my - the compiler won't flag it on an API change then, not 
ideal clearly. What's wrong with exporting kexec_in_progress()?

Best,
Jork
