samples/kobject: make kobj_type structure constant

2023-02-08T12:34:41+00:00

Since commit ee6d3dd4ed48 ("driver core: make kobj_type constant.") the driver core allows the usage of const struct kobj_type. Take advantage of this to constify the structure definition to prevent modification at runtime.

samples/kobject: Use sysfs_emit instead of sprintf

2022-03-18T13:28:29+00:00

sysfs_emit() is preferred over sprintf() when formatting the value to be returned to user space in show() functions, because it knows about sysfs buffer specifics and has sanity checks.

treewide: Add SPDX license identifier - Makefile/Kconfig

2019-05-21T08:50:46+00:00

Add SPDX license identifiers to all Make/Kconfig files which: - Have no license information of any form These files fall under the project license, GPL v2 only. The resulting SPDX license identifier is: GPL-2.0-only Signed-off-by: Thomas Gleixner Signed-off-by: Greg Kroah-Hartman

samples/kobject: Replace foo_ktype's default_attrs field with groups

2019-04-25T20:06:10+00:00

The kobj_type default_attrs field is being replaced by the default_groups field. Replace foo_ktype's default_attrs field with default_groups and use the ATTRIBUTE_GROUPS macro to create foo_default_groups. This patch was tested by loading the kset-example module and verifying that the sysfs files for the attributes in the default group were created.

kobject: Remove redundant license text

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

Now that the SPDX tag is in all kobject 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.

kobject: add SPDX identifiers to all kobject 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 kobject 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. Cc: Thomas Gleixner Cc: Kate Stewart Cc: Philippe Ombredanne Signed-off-by: Greg Kroah-Hartman

samples/kobject: be explicit in the module license

2015-03-25T12:41:42+00:00

Rusty pointed out that the module license should be "GPL v2" to properly match the notice at the top of the files, so make that change. Reported-by: Rusty Russell Signed-off-by: Greg Kroah-Hartman

samples/kobject: Use kstrtoint instead of sscanf

2015-03-25T12:40:31+00:00

Use kstrtoint function instead of sscanf and check for return values. Signed-off-by: Rastislav Barlik Signed-off-by: Greg Kroah-Hartman

samples/kobject/: avoid world-writable sysfs files.

2014-05-14T01:23:57+00:00

In line with practice for module parameters, we're adding a build-time check that sysfs files aren't world-writable. Cc: Greg Kroah-Hartman Signed-off-by: Rusty Russell

kobject: fix kset sample error path

2013-12-03T18:13:30+00:00

Previously, example_init() leaked a kset if any of the object creations failed. This fixes the leak by calling kset_unregister() in the error path. Signed-off-by: Bjorn Helgaas Signed-off-by: Greg Kroah-Hartman
