Subject: [PATCH] block: remove genhd.h
Git-commit: 322cbb50de711814c42fb088f6d31901502c711a
Patch-mainline: v5.18-rc1
References: jsc#PED-1183
There is no good reason to keep genhd.h separate from the main blkdev.h
header that includes it. So fold the contents of genhd.h into blkdev.h
and remove genhd.h entirely.
[hare: modified for SLE15 SP5 to patch drivers/dax/super.c]
