With recent linux-next i started to get this error:
[ 19.746764] EXT4-fs (sda6): Delayed block allocation failed for inode 4999023 at logical offset 0 with max blocks 6 with error 95
[ 19.746767] EXT4-fs (sda6): This should not happen!! Data will be lost
Bisect points at the commit e73c23ff736e ("block: add async variant of
blkdev_issue_zeroout") but i think that the real problem is a missed
break in the commit 2d253440b5af ("block: Define zoned block device
operations").
Fixes: 2d253440b5af ("block: Define zoned block device operations")
