Hi Linus,

A few small fixes that should go into the 6.15 kernel release. This pull
request contains:

- Reject zero sized legacy provided buffers upfront. No ill side effects
  from this one, only really done to shut up a silly syzbot test case.

- Fix for a regression in tag posting for registered files or buffers,
  where the tag would be posted even when the registration failed.

- 2 minor zcrx cleanups for code added this merge window.

Please pull!
