The Kconfig currently controlling compilation of this code is:

config FILE_LOCKING
     bool "Enable POSIX file locking API" if EXPERT

...meaning that it currently is not being built as a module by anyone.

Lets remove the couple traces of modularity so that when reading the
driver there is no doubt it is builtin-only.

Since module_init translates to device_initcall in the non-modular
case, the init ordering gets bumped to one level earlier when we
use the more appropriate fs_initcall here.  However we've made similar
changes before without any fallout and none is expected here either.

Looks fine to me and I doubt we'll see any merge conflicts with
anything I have queued so far. Do you need any of us to pick any of
these up or are you going to be merging them as a set?

I was hoping to spread as many of these around as possible so I don't
end up with a giant pull request to Linus.  There is code out there
without a clear maintainership path, so eventually I'll have to send
some his way (or via akpm) but the less that end up in that pile, the
better IMHO.

It looks like the hugetlb init level change upset one of the automated
qemu 0-day boot tests, so I need to investigate that next.

Paul.
