VRECYCLE(9) BSD Kernel Manual VRECYCLE(9)
vrecycle - recycle a vnode if its reference count is zero
#include <sys/param.h> #include <sys/vnode.h> int vrecycle(struct vnode *vp, struct simplelock *inter_lkp, struct proc *p);
The vrecycle() function places the vnode vp on the free list using vgonel(9) if its v_usecount field is zero. If v_usecount is non-zero, it simply returns. If v_usecount is zero and an interlock inter_lkp was passed, this interlock will be unlocked before calling vgonel(9).
vrecycle() will return 1 if the vnode was placed on the free list. It will return 0 if the reference count was non-zero, and any lock passed in inter_lkp will still be locked.
