block: remove blk_cleanup_disk

2022-06-28T12:33:15Z

blk_cleanup_disk is nothing but a trivial wrapper for put_disk now, so remove it. Signed-off-by: Christoph Hellwig Reviewed-by: Hannes Reinecke Link: https://lore.kernel.org/r/20220619060552.1850436-7-hch@lst.de Signed-off-by: Jens Axboe

m68k: Switch to new sys-off handler API

2022-05-19T17:30:30Z

Kernel now supports chained power-off handlers. Use register_power_off_handler() that registers power-off handlers and do_kernel_power_off() that invokes chained power-off handlers. Legacy pm_power_off() will be removed once all drivers will be converted to the new sys-off API. Normally arch code should adopt only the do_kernel_power_off() at first, but m68k is a special case because it uses pm_power_off() "inside out", i.e. pm_power_off() invokes machine_power_off() [in fact it does nothing], while it's machine_power_off() that should invoke the pm_power_off(), and thus, we can't convert platforms to the new API separately. There are only two platforms changed here, so it's not a big deal. Acked-by: Geert Uytterhoeven Reviewed-by: Michał Mirosław Signed-off-by: Dmitry Osipenko Signed-off-by: Rafael J. Wysocki

block: remove genhd.h

2022-02-02T14:49:59Z

There is no good reason to keep genhd.h separate from the main blkdev.h header that includes it. So fold the contents of genhd.h into blkdev.h and remove genhd.h entirely.

block: switch polling to be bio based

2021-10-18T12:17:36Z

Replace the blk_poll interface that requires the caller to keep a queue and cookie from the submissions with polling based on the bio. Polling for the bio itself leads to a few advantages: - the cookie construction can made entirely private in blk-mq.c - the caller does not need to remember the request_queue and cookie separately and thus sidesteps their lifetime issues - keeping the device and the cookie inside the bio allows to trivially support polling BIOs remapping by stacking drivers - a lot of code to propagate the cookie back up the submission path can be removed entirely.

put_tty_driver() is an alias for tty_driver_kref_put(). There is no need for two exported identical functions, therefore switch all users of old put_tty_driver() to new tty_driver_kref_put() and remove the former for good.

tty: stop using alloc_tty_driver

2021-07-27T10:17:20Z

alloc_tty_driver was deprecated by tty_alloc_driver in commit 7f0bc6a68ed9 (TTY: pass flags to alloc_tty_driver) in 2012. I never got into eliminating alloc_tty_driver until now. So we still have two functions for allocating drivers which might be confusing. So get rid of alloc_tty_driver uses to eliminate it for good in the next patch. Note we need to switch return value checking as tty_alloc_driver uses ERR_PTR. And flags are now a parameter of tty_alloc_driver.
