Then these two blocks of code should be factored out.

And after noting the above refactor, I'll also note that my previous comment
about 'modify_flags' applies here, too.

The check that follows this comment fetches the entry for db->name.
Specifically, it has a test for whether the entry exists. Given the above,
it definitely will exist. But more importantly, these two entry
manipulations should be folded together.
Specifically, the __entry_modify() is going to read the entries, but then it
will toss them out. But the following code will read the entries *again*.
Hmm. Further: the following check is to look for an obstructed update. I
would think that should happen *before* you go and create a new entry.
Especially because you might have a file sitting there and the above
modification would force that entry to a directory(!).
Cheers,
