[v2,0/2] New zoned loop block device driver

Message

Damien Le Moal Jan. 9, 2025, 8:50 a.m. UTC

The first patch implements the new "zloop" zoned block device driver
which allows creating zoned block devices using one regular file per
zone as backing storage.

The second patch adds documentation for this driver (overview and usage
examples).

About half of the code of the first patch is from Christoph Hellwig.

  Documentation: Document the new zoned loop block device driver

Changes from v1:
 - Corrected Kconfig description in patch 1 (outdated example was shown)
 - Added missing request sector update on completion of zone append
   request (I had not pushed that...)
 - Added reference to the documentation in the kconfig entry in patch 2
