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.

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

samples: mark {static|init|exit} for {init|exit} functions

2009-01-06T23:59:12+00:00

None of these (init|exit) functions is called from other functions which is outside the kernel module mechanism or kernel itself, so mark them as {static|__init|__exit}.

kobject: add sample code for how to use kobjects in a simple manner.

2008-01-25T04:40:41+00:00

This is a simple kobject module, showing how to use kobj_attributes in basic and more complex ways. Cc: Kay Sievers Signed-off-by: Greg Kroah-Hartman
