This was a question about Kernel Binary Inteface, not Application Binary Interface. First, we have zero guarantees about ability to load or have a system survive loading of the module compiled against the later kernel. Second, we do not have real KBI definition, and KBI stability is managed only ad-hock. E.g. VFS quite often breaks, while network or disk controllers drivers are usually fine. YMMV. Snobby false statements hurt the project. --mvWwdhJHqQXOQ5Pq Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (FreeBSD) iEYEARECAAYFAlA3DpEACgkQC3+MBN1Mb4gr6QCfVriy3QU9AKUjrzmU2Y08M+0v 454An0j5/2E98aW69Uh6zgmdkq575VJV =p8LN -----END PGP SIGNATURE----- --mvWwdhJHqQXOQ5Pq--
