I think the use of unlikely here and in pr_debug is unnecessary.

Shouldn't this be a module_table?

I think that hashing may be an unnecessary optimization and
that there's no real need to use a limited FILE_TABLE_SIZE
at all.  I think the most likely use cases for this facility
has either one or two modules being debugged or all modules
or no modules.
