NAME

     vget -- get a vnode from the free list

SYNOPSIS

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

     int
     vget(struct vnode *vp, int lockflag, struct thread *td);

DESCRIPTION

     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.
