I'll try this test.
zoned block device is bypassed in patch 14 by:
+ if (split && !bdev_is_zoned(bio->bi_bdev))
+ bio_list_add_head(¤t->bio_list[0], bio);
If I can find a reporducer for zoned block, and verify that recursive
split can be fixed as well, I can remove the checking for zoned devices
in the next verison.
Thanks,
Kuai
