     vget — get a vnode from the free list


     #include <sys/param.h>
     #include <sys/vnode.h>

     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)
