int
getnewvnode
(enum vtagtype tag,
struct mount *mp, const struct vops
*vops, 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:
getnewvnode
() returns 0 on success, or
ENFILE if the vnode table is full.
