From fdd0311863b32b42bb2c54e60c987bbbabc0c430 Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Sun, 5 Mar 2017 00:56:38 -0800 Subject: pstore: Replace arguments for write_buf_user() API Removes argument list in favor of pstore record, though the user buffer remains passed separately since it must carry the __user annotation.
