Subject: [PATCH 11/14] block: remove GENHD_FL_EXT_DEVT
Date: Mon, 22 Nov 2021 14:06:22 +0100	[thread overview]
Message-ID: <20211122130625.1136848-12-hch@lst.de> (raw)
In-Reply-To: <20211122130625.1136848-1-hch@lst.de>

All modern drivers can support extra partitions using the extended
dev_t.  In fact except for the ioctl method drivers never even see
partitions in normal operation.

So remove the GENHD_FL_EXT_DEVT and allow extra partitions for all
block devices that do support partitions, and require those that
do not support partitions to explicit disallow them using
GENHD_FL_NO_PART.
