41.Ft int
42.Fn VFS_VGET "struct mount *mp" "ino_t ino" "int flags" "struct vnode **vpp"
43.Sh DESCRIPTION
44The

50.It Fa mp

59.It Fa vpp
60Return parameter for the vnode.

63This is an optional file system entry-point for file systems mainly
64intended for NFS server use, but many file systems
65use it internally in
66.Xr VOP_LOOKUP 9
67and similar.
68.Pp
69If the file system does not support this call, then it should return
70.Er EOPNOTSUPP .
