Martin Matuska	83b4af1142	ZFS expects a copyout of zfs_cmd_t on an ioctl error. Our sys_ioctl() ... doesn't copyout in this case. To solve this issue a new struct zfs_iocparm_t is introduced consisting of: - zfs_ioctl_version (future backwards compatibility purposes) - user space pointer to zfs_cmd_t (copyin and copyout) - size of zfs_cmd_t (verification purposes) The copyin and copyout of zfs_cmd_t is now done the illumos (vendor) way what makes porting of new changes easier and ensures correct behavior if returning an error.
