Subject: btrfs: zoned: print message when zone sanity check type fails
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=f5741359c85128f06e673b4455b9f67043f9ac59;p=users%2Fjedix%2Flinux-maple.git

btrfs: zoned: print message when zone sanity check type fails

This extends patch 784daf2b9628 ("btrfs: zoned: sanity check zone
type"), the message was supposed to be there but was lost during merge.
We want to make the error noticeable so add it.

Fixes: 784daf2b9628 ("btrfs: zoned: sanity check zone type")
