VREF(9) BSD Kernel Manual VREF(9)
vref - increment the use count for a vnode
#include <sys/param.h> #include <sys/vnode.h> void vref(struct vnode *vp);
Increment the v_usecount field of the vnode specified by vp. Each vnode maintains a reference count of how many parts of the system are using the vnode. This allows the system to detect when a vnode is no longer being used and can be safely recycled for a different file. Any code in the system which uses a vnode (e.g. during the operation of some algorithm or to store in a data structure) should call vref().
