getnewvnode - get a new vnode

int
getnewvnode(enum vtagtype tag, struct mount *mp,
int (**vops) __P((void *)), struct vnode **vpp);
The getnewvnode() function initializes a new vnode, assigning it the vnode
operations passed in vops. It will have its v_tag field
set to tag
and be placed in the mount queue for the mount point represented by mp.
The vnode is either freshly allocated, taken from the free
list or taken
from the hold list. If there are no vnodes on the free
list, half the
time a vnode referencing buffers will be taken from the hold
list, otherwise
it will be freshly allocated.
The arguments to getnewvnode() are:
tag The file system type.
mp The mount point to add the new vnode to.
vops The vnode operations to assign to the new vnode.
vpp Points to the new vnode upon successful completion.
getnewvnode() returns 0 on success, or ENFILE if the vnode
table is full.
