Subject: [PATCH 10/12] docs: path-lookup: update WALK_GET, WALK_PUT desc
Date: Tue, 26 Jan 2021 15:24:41 +0800 [thread overview]
Message-ID: <20210126072443.33066-11-foxhlchen@gmail.com> (raw)
In-Reply-To: <20210126072443.33066-1-foxhlchen@gmail.com>
WALK_GET is changed to WALK_TRAILING with a different meaning.
Here it should be WALK_NOFOLLOW. WALK_PUT dosn't exist, we have
WALK_MORE.
WALK_PUT == !WALK_MORE
And there is not should_follow_link().
