We should just go for the simpler create/nocreate solution, I
prefer
that. This is too involved, and it's hard to get all the cases
right
since there are a bunch of different ways that files are added.
Which
was why this patch only focused on filename=, since that is the one
that
is the most interesting. But it still isn't pretty. If we add the
allow_file_create option, it's basically a two-liner change in a
few
places to not use O_CREAT.
That took roughly 4 minutes... Does this work? Set
allow_file_create=0
to disallow creating new files.

OK, let me test that, will spin a new one.
I don't think this ever got added.
It didn't... Did you re-test? No reason we can't get it added, I'll look
into it start next week.
Robert, I added this. Can you check current -git and see if it behaves
as expected for you?
Looks good. Adding
allow_file_create=0
prevents it from creating files in /dev when the specified path
does not exist and size= is specified.

Perfect, thanks for (re) testing.
