[PATCH 0/5] brd: Allow to change block sizes

[Hannes Reinecke <hare@suse.de>]

Hi all,

meat to the bone: with this patchset one can change the physical and
logical block size of the 'brd' ramdisk driver.
Default is 512 (for both); one can easily increase the physical block
size to 16k and the logical block size to 4k.
Increasing the logcial block size beyond 4k gives some 'interesting'
crashes.
It should also be possible to use the resulting ram disk as a backend
for nvme target, thereby exercising the NVMe stack for larger block
sizes, too.

Happy hacking!

Hannes Reinecke (5):
  brd: convert to folios
  brd: abstract page_size conventions
  brd: make sector size configurable
  brd: limit maximal block size to 32M
  brd: make logical sector size configurable
