Backends can either update the field during read(), or use the field during write() instead of fetching time themselves. Signed-off-by: Kees Cook <keescook@chromium.org>

pstore: Remove write_buf() callback 2017-03-07T22:01:02+00:00 Kees Cook keescook@chromium.org 2017-03-06T06:41:10+00:00 4c9ec219766a217468fb94a281c416455a884dda Now that write() and write_buf() are functionally identical, this removes write_buf(), and renames write_buf_user() to write_user(). Additionally adds sanity-checks for pstore_info's declared functions and flags at registration time. Signed-off-by: Kees Cook <keescook@chromium.org>
