Similarly provide a custom is_kdump_kernel() implementation that will only

Update the documentation of is_dump_available().

A small typo here:

is_dump_available() -> dump_available()

Here is a typo in the condition, a redundant '!' before is_ipl_type_dump().


Thanks for catching these! Too much going back and forth ... :)

Otherwise, looks very good to me.

Thanks for the fast review. I assume these can be fixed up when applying. But please let me know if a v3 is preferred, and I can send one after waiting a couple of days.
