But the answer is yes anyway. It's up to the filesystem to check whether it is allowed. FUSE does not block it and if the actual userland driver does not protest either, it is possible. >[...] ---------------------------------------------------------------------------= ---- Jan 'Bulb' Hudec --KFztAG8eRSV9hGtP Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.0 (GNU/Linux) iD8DBQFCXRevRel1vVwhjGURAivlAJ9ztjXm6w7r1Z7pbzZQxFcSWB+3TACfdOdh V8rTjcH99LsQjVyfFqnD4VY= =vEtJ -----END PGP SIGNATURE----- --KFztAG8eRSV9hGtP-- - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
