block: remove genhd.h

2022-02-02T14:49:59+00:00

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.

drivers: base: fix some kernel-doc markups

2020-11-09T17:56:49+00:00

class_create is actually defined at the header. Fix the
markup there and add a new one at the right place.

While here, also fix some markups for functions that have
different names between their prototypes and kernel-doc
comments.

drivers core: Miscellaneous changes for sysfs_emit

2020-10-02T11:12:07+00:00

Change additional instances that could use sysfs_emit and sysfs_emit_at
that the coccinelle script could not convert.

o macros creating show functions with ## concatenation
o unbound sprintf uses with buf+len for start of output to sysfs_emit_at
o returns with ?: tests and sprintf to sysfs_emit
o sysfs output with struct class * not struct device * arguments

Miscellanea:

o remove unnecessary initializations around these changes
o consistently use int len for return length of show functions
o use octal permissions and not S_
o rename a few show function names so DEVICE_ATTR_ can be used
o use DEVICE_ATTR_ADMIN_RO where appropriate
o consistently use const char *output for strings
o checkpatch/style neatening

device.h: move 'struct class' stuff out to device/class.h

2019-12-16T09:11:14+00:00

device.h has everything and the kitchen sink when it comes to struct
device things, so split out the struct class things things to a separate
.h file to make things easier to maintain and manage over time.

driver core: move device->knode_class to device_private

2019-01-18T15:55:48+00:00

As the description of struct device_private says, it stores data which
is private to driver core. And it already has similar fields like:
knode_parent, knode_driver, knode_driver and knode_bus. This look it is
more proper to put knode_class together with those fields to make it
private to driver core.

This patch move device->knode_class to device_private to make it comply
with code convention.

driver core: Remove redundant license text

2017-12-07T17:36:44+00:00

Now that the SPDX tag is in all driver core files, that identifies the
license in a specific and legally-defined manner.  So the extra GPL text
wording can be removed as it is no longer needed at all.

This is done on a quest to remove the 700+ different ways that files in
the kernel describe the GPL license text.  And there's unneeded stuff
like the address (sometimes incorrect) for the FSF which is never
needed.

No copyright headers or other non-license-description text was removed.

driver core: add SPDX identifiers to all driver core files

2017-12-07T17:36:43+00:00

It's good to have SPDX identifiers in all files to make it easier to
audit the kernel tree for correct licenses.

Update the driver core files files with the correct SPDX license
identifier based on the license text in the file itself.  The SPDX
identifier is a legally binding shorthand, which can be used instead of
the full boiler plate text.

This work is based on a script and data from Thomas Gleixner, Philippe
Ombredanne, and Kate Stewart.

driver core: remove class_attrs from struct class

2017-06-09T08:41:00+00:00

This field is no longer used or needed (use class_groups instead), so it
can be removed along with the driver core functionality that created and
removed these files.

driver core: class: add class_groups support

2016-11-29T20:12:12+00:00

struct class needs to have a set of default groups that are added, as
adding individual attributes does not work well in the long run.  So add
support for that.

Future patches will convert the existing usages of class_attrs to use
class_groups and then class_attrs will go away.
