I doubt that there is any list (Greg KH - and lots of other people
around - knowns way much more of the kernel than /me sp listen to them
if in doubt).
Especially since it is quite unclear what you mean with "my
descriptors".
- All file descriptors of your driver (excluding dup(), dup2() and
  dup-through-fork())
- All file descriptors of one device of your driver (excluding dup(),
  dup2() and dup-through-fork())

And BTW your driver has no chance to get to know if user-space dup()s,
dup2()s or fork()s (and thus also dup()s a file descriptor).
