driver core: make struct class.devnode() take a const *

2022-11-24T16:12:27Z

The devnode() in struct class should not be modifying the device that is passed into it, so mark it as a const * and propagate the function signature changes out into all relevant subsystems that use this callback.

aoe: Avoid flush_scheduled_work() usage

2022-05-01T12:41:41Z

Flushing system-wide workqueues is dangerous and will be forbidden. Replace system_wq with local aoe_wq.

aoe: use bvec_kmap_local in bvcpy

Using local kmaps slightly reduces the chances to stray writes, and the bvec interface cleans up the code a little bit. Signed-off-by: Christoph Hellwig Link: https://lore.kernel.org/r/20220303111905.321089-3-hch@lst.de Signed-off-by: Jens Axboe

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.
