So, although removing the lock here is pretty straightforward, it does

really get us closer to that goal IMHO, if that is what we want to do

end.
But it doesn't get us further either, right? This patch shouldn't make
any plan for range locking any worse. Both adding and removing a sparse
section is pfn range defined unless I am missing something.
Yes, you are right, it should not have any impact.
It just felt like "we do already have the global lock, so let us stick
with that".
But the less unneeded locks we have in our way, the better.
Sorry for the confusion.
