2013-12-19drivers: block: Mark the functions as static in skd_main.cRashika Kheria
Mark functions skd_skmsg_state_to_str() and skd_skreq_state_to_str() as static in skd_main.c because they are not used outside this file. This eliminates the following warnings in skd_main.c: drivers/block/skd_main.c:5272:13: warning: no previous prototype for ‘skd_skmsg_state_to_str’ [-Wmissing-prototypes] drivers/block/skd_main.c:5284:13: warning: no previous prototype for ‘skd_skreq_state_to_str’ [-Wmissing-prototypes] Signed-off-by: Rashika Kheria <rashika.kheria@gmail.com> Reviewed-by: Josh Triplett <josh@joshtriplett.org> Signed-off-by: Jens Axboe <axboe@kernel.dk>
2013-11-08skd: reorder construct/destruct codeBartlomiej Zolnierkiewicz
Reorder placement of skd_construct(), skd_cons_sg_list(), skd_destruct() and skd_free_sg_list() functions. Then remove no longer needed function prototypes.

2013-11-08skd: cleanup skd_do_inq_page_da()Bartlomiej Zolnierkiewicz
skdev->pdev and skdev->pdev->bus are always different than NULL in skd_do_inq_page_da() so simplify the code accordingly. Also cache skdev->pdev value in pdev variable while at it.

2013-11-08skd: remove redundant skdev->pdev assignment from skd_pci_probe()Bartlomiej Zolnierkiewicz
skdev->pdev is set to pdev twice in skd_pci_probe(), first time through skd_construct() call and the second time directly in the function. Remove the second assignment as it is not needed.

2013-11-08skd: register block device only if some devices are presentBartlomiej Zolnierkiewicz
Register block device in skd_pci_probe() instead of in skd_init() so it is registered only if some devices are present (currently it is always registered when the driver is loaded). Please note that this change depends on the fact that register_blkdev(0, ...) never returns 0.

2013-11-08skd: fix unregister_blkdev() placementBartlomiej Zolnierkiewicz
register_blkdev() is called before pci_register_driver() in skd_init() so unregister_blkdev() should be called after pci_unregister_driver() in skd_exit(). Fix it.

2013-11-08skd: more removal of bio-based codeMike Snitzer
Remove skd_flush_cmd structure and skd_flush_slab. Remove skd_end_request wrapper around skd_end_request_blk. Remove skd_requeue_request, use blk_requeue_request directly. Cleanup some comments (remove "bio" info) and whitespace. Signed-off-by: Mike Snitzer <snitzer@redhat.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
2013-11-08skd: cleanup the skd_*() function block wrappingJens Axboe
Just call the block functions directly, don't wrap them in skd helpers. With only one queueing model enabled, there's no point in doing that. Also kill the ->start_time and ->bio from the skd_request_context, we don't use those anymore. Signed-off-by: Jens Axboe <axboe@kernel.dk>
2013-11-08skd: rip out bio pathJens Axboe
The skd driver has a selectable rq or bio based queueing model. For 3.14, we want to turn this into a single blk-mq interface instead. With the immutable biovecs being merged in 3.13, the bio model would need patches to even work. So rip it out, with a conversion pending for blk-mq in the next release.

This patch fixes checkpatch.pl errors for assignment in if condition. It also removes unused readq / readl function calls. As Andrew had disabled the compilation of drivers for 32 bit, I have modified format specifiers in few VPRINTKs to avoid warnings during 64 bit compilation.
