[Stephen Rothwell]

Hi all,

After merging the mm tree, today's linux-next build (htmldocs) produced
these warnings:

Documentation/core-api/refcount-vs-atomic.rst:90: WARNING: Title underline too short.

case 2) - non-"Read/Modify/Write" (RMW) ops with release ordering
------------------------------------------- [docutils]
Documentation/core-api/refcount-vs-atomic.rst:142: WARNING: Title underline too short.

case 6) - increment-based RMW ops with acquire ordering that return a value
----------------------------------------------------- [docutils]

Introduced by commit

  03b412c8b184 ("refcount: provide ops for cases when object's memory can be reused")
