From 18edb95a88a947b10536be4dc86b4a190715f816 Mon Sep 17 00:00:00 2001 From: Fox Chen Date: Thu, 27 May 2021 17:16:14 +0800 Subject: [PATCH] docs: path-lookup: no get_link() no get_link() anymore. we have step_into() and pick_link(). walk_component() will call step_into(), in turn call pick_link, and return symlink name.
