Commit Message

  Ross reported broken link to BTF documentation
(Documentation/bpf/btf.rst) in Documentation/bpf/bpf_devel_QA.rst. The
link in question is written using external link syntax, with the target
refers to BTF doc in reST source (btf.rst), which doesn't exist in
resulting HTML output.

Fix the link by replacing external link syntax with simply writing out
the target doc, which the link will be generated to the correct HTML doc
target.

Fixes: 6736aa793c2b5f ("selftests/bpf: Add general instructions for test execution")
Reported-by: Ross Zwisler <zwisler@google.com>
Signed-off-by: Bagas Sanjaya <bagasdotme@gmail.com>
---
Changes since v1 [1]:

  * Reword patch description (I don't see external link semantics on
    Sphinx documentation [2] when I submit v1).
  * Drop the corresponding orphan target definition.
  * Rebase on top of current bpf tree.

Ross, do you want to give a Reviewed-by or Acked-by?

Applied, thanks! Looks like kselftest.rst has a similar issue, could you
send a fix for this too?
