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.
