Commits 0fc1fdb0 ("fetch_populated_submodules: use new parallel job
processing", 28-09-2015) and 60f24f52 ("run-command: add an asynchronous
parallel child processor", 28-09-2015) both introduce external symbols
which only require file scope visibility. In order to reduce the
visibility, apply the static keyword to their declarations.

Hi Stefan,

No, despite the same subject, this is not the same patch that I sent
you last week! :-D

Could you please squash parts of this into the patches corresponding
to the above mentioned commits.

Thanks!

BTW, I would once again suggest that you could move the definition of
get_next_submodule() to be above/before fetch_populated_submodules()
so that you can remove the forward declaration.

ATB,
Ramsay Jones

I am sorry for the need to send this second patch. :(

I thought I had this in yesterdays reroll (v6). Oh you're referring to
the version
from the 28th (I forgot to label them v5 I suppose).

I will also get rid of the forward declaration.

Ah! I thought I'd seen it on the list. (I thought I was going crazy) ;-)
Sorry, my fault. I just assumed that today's pu branch would have your
latest patches - I didn't actually check that.

Note that the first hunk, above, is actually new (I hadn't noticed it
before).

Thanks!

Sometimes I take a one-day vacation ;-)

Thanks.
