VPUT(9)			 BSD Kernel Developer's Manual		       VPUT(9)

NAME
     vput — Decrement the primary reference count for a vnode and unlock it

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

     void
     vput(struct vnode *vp);

DESCRIPTION
     Decrement the vnode's primary reference count (via the v_sysref field)
     and unlock the vnode.

     vp	 The vnode in question.

     This operation is functionally equivalent to calling vn_unlock(9) fol‐
     lowed by vrele(9).	 Releasing the last primary reference on a vnode will
     cause it to be deactivated and either moved to the free list or cached.
     Vnodes with namecache and/or VM objects are typically marked as being
     cached unless the system needs the memory for other purposes.

SEE ALSO
     vdrop(9), vget(9), vhold(9), vnode(9), vn_lock(9), vn_unlock(9), vref(9),
     vrele(9)
