[PATCH linux-next 1/8] pstore/ram: Standardize module name in ramoops

From: Kees Cook
Date: Thu Nov 01 2018 - 19:52:10 EST


With both ram.c and ram_core.c built into ramoops.ko, it doesn't make
sense to have differing pr_fmt prefixes. This fixes ram_core.c to use
the module name (as ram.c already does). Additionally improves region
reservation error to include the region name.
