From 0d625446d0a451a683a357799912b9e688629707 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Thu, 1 Jun 2023 16:58:53 +0200 Subject: backing_dev: remove current->backing_dev_info Patch series "cleanup the filemap / direct I/O interaction", v4. This series cleans up some of the generic write helper calling conventions and the page cache writeback / invalidation for direct I/O. This is a spinoff from the no-bufferhead kernel project, for which we'll want to an use iomap based buffered write path in the block layer. This patch (of 12): The last user of current->backing_dev_info disappeared in commit b9b1335e6403 ("remove bdi_congested() and wb_congested() and related functions"). Remove the field and all assignments to it.
