Hi,
unfortunately commit e36f62042880 "block: split bios to maxpossible length"
breaks the DASD driver on s390. We expect the block requests to be multiple
of 4k in size. With the patch applied I see the requests split up in
multiple
of 512 byte and therefore the requests get rejected and lots of I/Os fail.
Could you please fix or revert the patch?
We have following values set for the block queue:
hw_sector_size 4096
logical_block_size 4096
minimum_io_size 4096
physical_block_size 4096
max_hw_sectors_kb 760
max_sectors_kb 760
max_segment_size 4096
max_segments 65535
Regards,
Stefan
