Subject: [PATCH 2/2] kstrto*: do not  describe simple_strto*() as  obsolete/replaced
Date: Fri, 31 Jul 2020 00:40:29 +0200
Message-ID: <29b9-5f234c80-13-4e3aa200@244003027> (raw)
In-Reply-To: <1ee1-5f234c00-f3-165a6440@234394593>

The documentation of the kstrto*() functions describes kstrto*() as
"replacements" of the "obsolete" simple_strto*() functions. Both of
these terms are inaccurate: they're not replacements because they have
different behaviour, and the simple_strto*() are not obsolete because
there are cases where they have benefits over kstrto*().

Remove usage of the terms "replacement" and "obsolete" in reference
to simple_strto*(), and instead use the term "preferred over".

Fixes: 4c925d6031f71 ("kstrto*: add documentation")
Fixes: 885e68e8b7b13 ("kernel.h: update comment about simple_strto<foo>() functions")
