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


#include <sys/param.h> #include <sys/vnode.h> void vput(struct vnode *vp);


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.
