Commit Message

Christoph Hellwig June 11, 2024, 5:19 a.m. UTC 
Since commit 7437bb73f087 ("block: remove support for the host aware zone
model"), only ZBC devices expose a zoned access model.  sd_is_zoned is
used to check for that and thus return false for host aware devices.

Fixes: 7437bb73f087 ("block: remove support for the host aware zone model")
