From 1442f76d4317b420580e11238d20789708c742a4 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 24 Mar 2020 08:25:26 +0100 Subject: block: move struct partition out of genhd.h struct partition is the on-disk format of a MSDOS partition table entry. Move it out of genhd.h into a new msdos_partition.h header and give it a msdos_ prefix to avoid confusion. Also move the magic number from block/partitions/msdos.h to the new header so that it can be used by the SCSI drivers looking at the DOS partition tables.
