Maybe you can deny to open such files with proxy file ops and proxy
block dev ops.

So you implement all file operations and just give back errors.
This has no speed penalty for the hot path and implements correct error
handling.

Only penalty is code bloat, but this is normal for additional error
handling ;-)


But maybe I'm totally wrong here and this is just another case of
"doctor it hurts...".
