Hi all,

After merging the block tree, today's linux-next build (x86_64
allmodconfig) failed like this:

block/blk-zoned.c: In function 'blk_zone_write_plug_bio_endio':
block/blk-zoned.c:1260:25: error: 'struct block_device' has no member named 'bd_has_submit_bio'
1260 | if (bio->bi_bdev->bd_has_submit_bio)
| ^~
block/blk-zoned.c: In function 'blk_zone_wplug_bio_work':
block/blk-zoned.c:1329:17: error: 'struct block_device' has no member named 'bd_has_submit_bio'
1329 | if (bdev->bd_has_submit_bio)
| ^~

Caused by commit

dd291d77cc90 ("block: Introduce zone write plugging")

interacting with commit

ac2b6f9dee8f ("bdev: move ->bd_has_subit_bio to ->__bd_flags")

from the vfs tree.

I have applied the following merge resolution patch.

From: Stephen Rothwell <sfr@canb.auug.org.au>
Date: Fri, 10 May 2024 12:59:09 +1000
Subject: [PATCH] fix up for "bdev: move ->bd_has_subit_bio to ->__bd_flags"

interacting with "block: Introduce zone write plugging".
