Patch already reached upstream. So, it gained a stable reference.
So, I'm changing its description to:

locking/refcount: move kernel-doc markups to the proper place
Changeset a435b9a14356 ("locking/refcount: Provide __refcount API to obtain the old value")
added a set of functions starting with __ that have a new
parameter, adding a series of new warnings:
$ ./scripts/kernel-doc -none include/linux/refcount.h
include/linux/refcount.h:169: warning: Function parameter or member 'oldp' not described in '__refcount_add_not_zero'
include/linux/refcount.h:208: warning: Function parameter or member 'oldp' not described in '__refcount_add'
include/linux/refcount.h:239: warning: Function parameter or member 'oldp' not described in '__refcount_inc_not_zero'
include/linux/refcount.h:261: warning: Function parameter or member 'oldp' not described in '__refcount_inc'
include/linux/refcount.h:291: warning: Function parameter or member 'oldp' not described in '__refcount_sub_and_test'
include/linux/refcount.h:327: warning: Function parameter or member 'oldp' not described in '__refcount_dec_and_test'
include/linux/refcount.h:347: warning: Function parameter or member 'oldp' not described in '__refcount_dec'
The issue is that the kernel-doc markups are now misplaced,
as they should be added just before the functions.
So, move the kernel-doc markups to the proper places,
in order to drop the warnings.
It should be noticed that git show produces a crappy output,
for this patch without "--patience" flag.
Fixes: a435b9a14356 ("locking/refcount: Provide __refcount API to obtain the old value")

If ok for you, I should be sending it upstream on a next pull request
for the documentation warning fix series.

Mauro
