2020-02-25docs: kref: Clarify the use of two kref_put() in example codeManivannan Sadhasivam
Eventhough the current documentation explains that the reference count gets incremented by both kref_init() and kref_get(), it is often misunderstood that only one instance of kref_put() is needed in the example code. So let's clarify that a bit. Signed-off-by: Manivannan Sadhasivam <manivannan.sadhasivam@linaro.org> Signed-off-by: Jonathan Corbet <corbet@lwn.net>
2017-07-14kref.txt: standardize document formatMauro Carvalho Chehab
Each text file under Documentation follows a different format. Some doesn't even have titles! Change its representation to follow the adopted standard, using ReST markups for it to be parseable by Sphinx: - add a title for the document and section titles; - move authorship information to the beginning and use :Author: - mark literal blocks as such and ident them if needed.
