the right thing. Can you send a proper patch with a proper signoff?

Absolutely, thanks for the guidance. You're right that Option B is the
correct approach for consistency and security.

I've prepared the patch below. It adds CAP_SYS_RAWIO check to
ioctl_fiemap() to match the protection already in place for FIBMAP.

The check is placed early in the function, before any filesystem-specific
operations, following the same pattern as ioctl_fibmap().
