Hello, We are registering bio size of our device with linux kernel with below available kernel API. blk_queue_max_hw_sectors(dev->osdev.queue, (dev->aggr_max_size >> KERNEL_SECTOR_SHIFT));.
Max size of bio that our block device can handle is 106496 bytes (104KB) but linux block device is sending 262144 bytes (256 KB) which is more than we are registering with kernel. This issue we are observing in 4.4.0-59-generic kernel version. Until this we had not seen this issue. So does anything extra require to tell linux kernel or anything else need to register ?
