If the underlying device is not a multiple of `BLK_MIG_BLOCK_SIZE`, the write will fail with -EIO when trying to write past the end of the device, as `blk_check_byte_request` checks the length of the device. - -This can be fixed by ensuring that `cur_addr` + write length passed to `blk_pwrite`/`blk_pwrite_zeroes` never exceeds the total length of the block device. |
