Well, maybe! What I'd really like is to remove all the markup from xarray.rst. Jon managed to get rid of most of it with the (), but there's still markup on: LONG_MAX NULL -EBUSY true XA_MARK_[012] XA_FLAGS_* ENOMEM EINVAL I'm not sure there's much that automarkup can do about ``true``, but all the others fit the all-caps-and-underscore-and-digits pattern. I don't know how much we want errnos to link to anything in particular. So maybe split these into 'well-known' (eg defined by ANSI C or POSIX) definitions and things which are local macros: LONG_MAX NULL -EBUSY ENOMEM EINVAL vs XA_MARK_[012] XA_FLAGS_* I'm willing to add more inline kernel-doc to get this to work better. Or even convert #defines to enums ... whatever gets this working better. > At the moment, this automarkup script is being used only for cross-referencing, > but it is indeed a generic automarkup script, and could be used for the > formatting of NULL.

I think this works well, except that we need to match not just NULL but other well-known ANSI/POSIX keywords. Thanks for entertaining this!
