generic_start_io_acct/generic_end_io_acct in the master branch of the linux kernel requires that the request_queue be provided. Move the logic from freemem in the spl to arc_free_memory in arc.c. Do this so we can take advantage of global_page_state interface checks in zfs. Upstream kernel replaced struct block_device with struct gendisk in struct bio. Determine if the function bio_set_dev exists during configure and have zfs use that if it exists. bio_set_dev https://github.com/torvalds/linux/commit/74d4699 global_node_page_state https://github.com/torvalds/linux/commit/75ef718 io acct https://github.com/torvalds/linux/commit/d62e26b Reviewed-by: Brian Behlendorf <behlendorf1@llnl.gov> Signed-off-by: Giuseppe Di Natale <dinatale2@llnl.gov> Closes #6635 Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov>
