Hi Jens,
this series switches back from storing the gendisk + partno to storing
a block_device pointer in struct bio. The reason is two fold: for one
the new struct block_device actually is always available, removing the
need to avoid originally. Second the merge struct block_device is much
more useful than the old one, as storing it avoids the need for looking
up what used to be hd_struct during partition remapping and I/O
accounting.
Note that this series depends on the posted but not merged
"split hard read-only vs read-only policy" series.

Changes since v1:
- protect against double remapping I/O to partitions

The block layer already checks for this conditions in bio_check_eod

Replace the gendisk pointer in struct bio with a pointer to the newly
improved struct block device. From that the gendisk can be trivially
accessed with an extra indirection, but it also allows to directly
look up all information related to partition remapping.

* [dm-devel] [PATCH 03/10] block: store a block_device pointer in struct bio
@ 2021-01-24 10:02 ` Christoph Hellwig

From: Christoph Hellwig @ 2021-01-24 10:02 UTC (permalink / raw)
To: Jens Axboe
Cc: linux-s390, linux-bcache, Coly Li, linux-raid, Song Liu,
dm-devel, linux-block, Tejun Heo
Replace the gendisk pointer in struct bio with a pointer to the newly
improved struct block device. From that the gendisk can be trivially
accessed with an extra indirection, but it also allows to directly
look up all information related to partition remapping.

There is no good reason to reassign ->bi_bdev when remapping the
partition-relative block number to the device wide one, as all the
information required by the drivers comes from the gendisk anyway.
Keeping the original ->bi_bdev alive will allow to greatly simplify
the partition-away I/O accounting.

There is good reason to iterate backwards when deleting all partitions in
del_gendisk, just like we don't in blk_drop_partitions.

Now that no fast path lookups in the partition table are left, there is
no point in micro-optimizing the data structure for it. Just use a bog
standard xarray.

* [dm-devel] [PATCH 10/10] block: use an xarray for disk->part_tbl
@ 2021-01-24 10:02 ` Christoph Hellwig

Now that no fast path lookups in the partition table are left, there is
no point in micro-optimizing the data structure for it. Just use a bog
standard xarray.

.config attached - hard to share any output, as it seems to load the
kernel fine, but latter parts of the boot process end up with errors
after the screen blanks. It's a laptop, so nothing fancy in terms of
logging. FWIW, it did boot on my test box.
Let me try and do a video...

And the issue shows up with the series just up to the this patch,

Ok, I have an idea. With EOD message you mean this printk, right:
pr_info_ratelimited("attempt to access beyond end of device\n"
"%s: rw=%d, want=%llu, limit=%llu\n",
...
right?
