block: drop owner assignment from platform_drivers

2014-10-20T14:20:18+00:00

A platform_driver does not need to set an owner, it will be populated by the
driver core.

block: remove struct request buffer member

2014-04-15T20:03:02+00:00

This was used in the olden days, back when onions were proper
yellow. Basically it mapped to the current buffer to be
transferred. With highmem being added more than a decade ago,
most drivers map pages out of a bio, and rq->buffer isn't
pointing at anything valid.

Convert old style drivers to just use bio_data().

For the discard payload use case, just reference the page
in the bio.

drivers/block/swim.c: remove unnecessary platform_set_drvdata()

2013-09-11T22:56:59+00:00

The driver core clears the driver data to NULL after device_release or
on probe failure.  Thus, it is not needed to manually clear the device
driver data to NULL.

swim: Release memory region after incorrect return/goto

2013-06-24T17:44:19+00:00

The code uses

	return foo;
	goto err_type;

when instead the form should have been

	ret = foo;
	goto err_type;

Here this causes a useful release_mem_region to be skipped.

block_device_operations->release() should return void

2013-05-07T06:16:21+00:00

The value passed is 0 in all but "it can never happen" cases (and those
only in a couple of drivers) *and* it would've been lost on the way
out anyway, even if something tried to pass something meaningful.
Just don't bother.

swim: Add missing spinlock init

2013-02-09T13:23:33+00:00

It doesn't seem this spinlock was properly initialized.

Drivers: block: remove __dev* attributes.

2013-01-03T23:57:15+00:00

CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

block: unexport DISK_EVENT_MEDIA_CHANGE for legacy/fringe drivers

2011-04-21T19:33:05+00:00

In-kernel disk event polling doesn't matter for legacy/fringe drivers
and may lead to infinite event loop if ->check_events() implementation
generates events on level condition instead of edge.

Now that block layer supports suppressing exporting unlisted events,
simply leaving disk->events cleared allows these drivers to keep the
internal revalidation behavior intact while avoiding weird
interactions with userland event handler.

swim[3]: Convert to bdops->check_events()

2011-03-09T18:54:28+00:00

Convert from ->media_changed() to ->check_events().

Both swim and swim3 buffer media changed state and clear it on
revalidation.  They will behave correctly with kernel event polling.
