vget - get a vnode from the free list
vget(struct vnode *vp, int lockflag, struct thread *td);
Get a vnode from the free list and increment its reference count.
vp The vnode to remove from the free list.
lockflag If non-zero, the vnode will also be locked.
When not in use, vnodes are kept on a free list. The vnodes still
reference valid files but may be reused to refer to a new file at any
time. Often, these vnodes are also held in caches in the system, such as
the name cache.
When a vnode which is on the free list is used again, for instance if the
vnode was found in the name cache as a result of a call to VOP_LOOKUP(9)
then the new user must call vget() to increment the reference count and
remove it from the free list.
vnode(9), vput(9), vref(9), vrele(9)
