From d3c4a43d9291279c28b26757351a6ab72c110753 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 6 Apr 2021 08:22:55 +0200 Subject: block: refactor blk_drop_partitions Move the busy check and disk-wide sync into the only caller, so that the remainder can be shared with del_gendisk. Also pass the gendisk instead of the bdev as that is all that is needed.
