Correct me if I'm wrong: if user adds FSEXT for a particular
handle, then this function won't call its handler, it will call
readlink handler as an 'open' handler, right?

So I have to call single handler in two ways: this - 

if (func(__FSEXT_readlink, &rv, &blah, &blah,...))
    return rv;

and this:

if (__FSEXT_call_open_handlers(__FSEXT_readlink, &ret, &__path))

Will the same handler do well in both cases?

Tested. Works. readlink() part. fstat() part _will_ work, at first I have
to change fstat() to use it, then - debugging, testing, debugging... 
When it comes to FSEXT, I feel less confident.
