vnode_getparent
Get an iocount on the parent of a vnode.
Declaration
vnode_t vnode_getparent(vnode_t vp);Parameters
- vp:
The vnode whose parent to grab.
Return Value
Parent if available, else NULL.
Discussion
A vnode's parent may change over time or be reclaimed, so vnode_getparent() may return different results at different times (e.g. a multiple-hardlink file). The parent is returned with an iocount which must subsequently be dropped with vnode_put().
