Subject: [PATCH v2 00/12] docs: path-lookup: Update pathlookup docs

The Path lookup is a very complex subject in VFS. The path-lookup
document provides a very detailed guidance to help people understand
how path lookup works in the kernel. This document was originally
written based on three lwn articles five years ago. As times goes by,
some of the content is outdated. This patchset is intended to update
the document to make it more relevant to current codebase.

v1: https://lore.kernel.org/lkml/20210126072443.33066-1-foxhlchen@gmail.com/
v2:
 - Fix problems in v1 reviewed by Neil:
   1. In Patch 01 and 02 rewrite a new paragrah to describe step_into()
   2. In Patch 01 instead of changing it to traverse_mounts, remove follow_managed()
   3. In Patch 03 re-telling the story rather than adding notes
   4. In Patch 04 do_open() should be outside of loop, fix it and fix other problems
      in following paragrah
   5. In Patch 07 use "drop out of RCU-walk"
   6. In Patch 08 "latter" should be "later", fix it and restructure the next paragrah
      removing "Finally"

To help review, I've put a compiled html version here:
