Hi Christoph Hellwig, So 4.4.0-59-generic is not stable one ?. If not then probably it would be problem for us if customer want the same kernel version!. Thanks, Umesh -Original Message- From: Christoph Hellwig [mailto:h...@infradead.org] Sent: Thursday, March 2, 2017 9:34 PM To:

Hi Umesh, it's linux-bl...@vger.kernel.org, and the place where all block layer and driver development happens, you can subsribe to it using the same way you subscribed to linux-kernel, just replacing the list name. The latest released vesion at this point is Linux 4.10.

Please post your driver to the linux-block list, and test a recent kernel.

Hi Christoph Hellwig, Thanks for reply. BTW (since I'm new) what is linux-block list ?. Is it subscribe ?. Can you please let me know which is latest kernel version ? Thanks, Umesh -Original Message- From: Christoph Hellwig [mailto:h...@infradead.org] Sent: Thursday, March 2, 2017

Kernel bio layer is sending bio size more than our block device is capable of handling

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
