From 9cf766a457995a95d7f66d78cf749d05067d68a4 Mon Sep 17 00:00:00 2001 From: Christoph Böhmwalder Date: Fri, 13 Jan 2023 13:35:35 +0100 Subject: drbd: remove macros using require_context MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This require_context attribute originated in a proposed sparse patch by Philipp Reisner back in 2008. Johannes Berg had a different solution to a similar problem, and that patch "won" in the end; so the require_context thing never got merged. The whole history can be read at [0]. DRBD kept using these annotations anyway for a while. Nowadays, on a modern unmodified sparse, they obviously do nothing, and they are hardly used anymore anyway. So, just remove the definitions of these macros.
