>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.
