Actually that is not enough to fix the inconsistent access to the
object store: the functions is_submodule_active() and
repo_submodule_init() too end up calling config_from_gitmodules() and
need protecting as well, so I am going to put them under the git read
lock and leave repo_read_gitmodules() in place for now.
Removing unneeded code can go in a possible stand-alone patch.

Just to double check: are you referring to *nested* submodules in the
sentence above?
I am asking because the whole point of this patchset is to *enable* the
use of submodules without .gitmodules in the working tree of the
superproject. :)
It's just that current limitations in git do not allow to support this
for *nested* submodules yet.

Let's see how v6 turns out.
