From 76cc9580e3fbd323651d06e8184a5a54e0e1066e Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Fri, 3 Mar 2017 23:28:53 -0800 Subject: pstore: Replace arguments for write() API Similar to the pstore_info read() callback, there were too many arguments. This switches to the new struct pstore_record pointer instead. This adds "reason" and "part" to the record structure as well.
