/*
* XXXPJD: zfs_zget() can't operate on virtual entires like .zfs/ or
* .zfs/snapshot/ directories, so for now just return EOPNOTSUPP.
* This will make NFS to fall back to using READDIR instead of
* READDIRPLUS.
* Also snapshots are stored in AVL tree, but based on their names,
* not inode numbers, so it will be very inefficient to iterate
* over all snapshots to find the right one.
* Note that OpenSolaris READDIRPLUS implementation does LOOKUP on
* d_name, and not VGET on d_fileno as we do.
* zfs_zget() can't operate on virtual entires like .zfs/ or
* .zfs/snapshot/ directories, that's why we return EOPNOTSUPP.
* This will make NFS to switch to LOOKUP instead of using VGET.
