Subject: [PATCH v3 01/13] docs: path-lookup: update follow_managed() part
Date: Thu, 27 May 2021 17:16:06 +0800	[thread overview]
Message-ID: <20210527091618.287093-2-foxhlchen@gmail.com> (raw)
In-Reply-To: <20210527091618.287093-1-foxhlchen@gmail.com>

No follow_managed() anymore, handle_mounts(),
traverse_mounts(), will do the job.
see commit 9deed3ebca24 ("new helper: traverse_mounts()")
