We have the version number for eons, but it is unusable because there is no defined VFS KPI. See VFS_VERSION in the sys/sys/mount.h and its use for the module loading and filesystem registrations. --mBuDz+cd8w/hvK2v Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.19 (FreeBSD) iQIcBAEBAgAGBQJQ3wSWAAoJEJDCuSvBvK1BRrYP/jQ6Sd+MGwOisM8YotsuIzBR S1keOAc3eKutEYUnSg7d/85AfcvkXe+J60LIIljbTw8S6mL9sDCWM+gQ9R57Gt9N 4alUH59M+YjBNKmbi/kza6vknwHN+Nh5xt42AITuNq856swnwZC7ozxmWaOXPf4i KPnIGgD2xjI+a24jHGnT4TBrDHtYYjQ7hH3L0gJNVUYhjjLkoE9EpPZfQNoOltYH oAaX9eEaCQM5kmOKRXNtOWsAM1JxaWFW6AUvoRSbfWpWK0hSnB5ZBvsuEu634bJS zG+xHC9BV3y+HWmgwuN7wVrFQg8h+TS/f9a9tQ1bjno653hqMr6O7bG5iUpdkaai ffgtZdXHzMetku+/CLph3fAkvA56UIDGWu5OqKfo/oQiTaVqDpShFigVi6DMxZyg LYXwvZZ0exrrIkIWffOvN4bUp2qUz8mppuBiiWhRrf5X5UWIOZQ0LPLbpKcE5kpy AjtjVgnFYAKrlQ8ntsAA0jzDivi/eJCpDusFSAC4TcAsO8pGv1APf0dXdSbZL1o/ V7h1lGPnIbKEf5CQYivzXZaNyiKddkpfVnS3TfcWODwQl5u/QKSG6UEEGiQDI83j osDrCfq3ofMQNaCh/s+2SHrP0RLEKbgaSi9mvifIKtYywEI6CkTBpMFQjkc1Xtv8 wddck44otHEL4YU0f4zv =qk75 -----END PGP SIGNATURE----- --mBuDz+cd8w/hvK2v--
