*	Linux 3.14 compat: IO acct, global_page_state, etc	Giuseppe Di Natale	2017-09-16	1	-4/+31
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	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 <[email protected]> Signed-off-by: Giuseppe Di Natale <[email protected]> Closes #6635
*	Reintroduce IO accounting on zvols on Linux 3.19+	Richard Yao	2015-09-09	1	-0/+26
	zfsonlinux/zfs@e20cd6f7a8922709b1aa2ecefd783390102d79e0 caused us to lose IO accounting on zvols. When I originally wrote that last year, the symbols we needed to maintain IO accounting were GPL exported, but torvalds/linux@394ffa503bc40e32d7f54a9b817264e81ce131b4 provided suitable symbols for restoring this functionality 4 months later. We can call them to restore the IO accounting on Linux 3.19 and later as well as any older kernels where that patch is backported.
