>Description:
The first problem is that efi_block_find_partitions_gpt() and
efi_block_open() in some places use DEV_BSIZE sectors instead of
bdev->bio->Media->BlockSize. This is easy enough to fix and makes
GPT partitions appear in the partition list.

But there is still some problem with the strategy or file system
code because loading /netbsd ends with EIO after 5 or so I/Os.

>How-To-Repeat:
I'm using a Corsair Force MP300 NVMe disk, which was reformatted
to 4k sectors with Linux nvme-cli.

>Fix:
N/A
