[PATCH 2/4] kexec-tools: Introduce dbg_memrange() macro and make use of it

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



There are several places where memory range arrays are printed for debug
reasons. In load_crashdump_segments() the memory type is missing.

Unify printing memory ranges in --debug case in a macro and add the first
users.
