From a1548b674403c0de70cc29a1575689917ba60157 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Thu, 14 Nov 2019 15:34:34 +0100 Subject: block: move rescan_partitions to fs/block_dev.c Large parts of rescan_partitions aren't about partitions, and moving it to block_dev.c will allow for some further cleanups by merging it into its only caller.
