Please pull the following to get the removal of the original IBM PC-XT
hard disk driver from the block layer (drivers/block/xd.c).
As near as I can tell, it hasn't seen a run time fix in over a dozen
years, and with drive sizes of 10-20MB, and performance of about 128kB/s
maximum, it is no surprise that it has been completely unused for well
over a decade.
The removal was originally posted[1] well over a month ago, and since
then, there has been nobody objecting to the removal, aside from someone
who had mistakenly confused it with a completely different driver (hd.c)
This patch includes the device driver for the IBM RamSan
family of PCI SSD flash storage cards. This driver will
include support for the RamSan 70 and 80. The driver
presents a block device for device I/O.

This driver was for the 8 bit ISA cards that were installed in
the PC-XT machines of 1980 vintage. They supported the dual
ribbon cable MFM drives of 10-20MB capacity, and ran at a 3:1
interleave, giving performance on the order of 128kB/s.
By the introduction of the PC-AT (286) these controllers were
already scrapped in favour of 16 bit controllers with some onboard
RAM that could support a 1:1 interleave.
The git history doesn't show any evidence of runtime fixes that
would reflect active usage; instead just the usual tree-wide API
type changes/cleanups. Going back to in-source changelogs, the
last "runtime" fix that is evident is something I did over a
dozen years ago[1] -- and even back then, the hardware was long
since unavailable, so that ancient fix was also not runtime tested.
The time is long overdue for this to get flushed, so lets get
rid of it before anyone wastes more time doing builds and sparse
checks etc. on long since dead code.

With the frontend having Xen but the backend not, it just looks odd:
<*> Xen virtual block device support
<*> Block-device backend driver
Fix it to have the 'Xen' in front of it.

Instead of unconditionally creating a fixed number of dead loop
devices which need to be investigated by storage handling services,
even when they are never used, we allow distros start with 0
loop devices and have losetup(8) and similar switch to the dynamic
/dev/loop-control interface instead of searching /dev/loop%i for free
devices.

The rados block device (rbd), based on osdblk, creates a block device
that is backed by objects stored in the Ceph distributed object storage
cluster. Each device consists of a single metadata object and data
striped over many data objects.
The rbd driver supports read-only snapshots.

Submitted driver exports a block device of the form /dev/osdblkX,
where X is a decimal number.
It does that by mounting a stacking block device on top
of an osd object. For example, if you create a 2G object
on an OSD device, you can then use this module to present
that 2G object as a Linux block device.
See inside patch for exact documentation.

for this driver, thanks to Randy Dunlap]
