Re: Kernel bio layer is sending bio size more than our block device is capable of handling
>From the kernel source code i came to know below things. 4.1 kernel version onward *""nr_pages = min(sdio->pages_in_io, bio_get_nr_vecs(map_bh->b_bdev))""* line has been removed which was considering max_sectors_kb of queue. Now new code is something like this* "nr_pages = min(sdio->pages_in_io, BIO_MAX_PAGES)"*, which is sending 256 bytes of data to our device which we are not supporting. Please let me know is there any other place where i can register my max_sectors_kb to kernel. -- View this message in context: http://linux-kernel.2935.n7.nabble.com/Kernel-bio-layer-is-sending-bio-size-more-than-our-block-device-is-capable-of-handling-tp1381843p1381844.html Sent from the Linux Kernel mailing list archive at Nabble.com.

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!.

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.
