MirOS Manual: vrecycle(9)

VRECYCLE(9)                   BSD Kernel Manual                    VRECYCLE(9)

NAME

     vrecycle - recycle a vnode if its reference count is zero

SYNOPSIS

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

     int
     vrecycle(struct vnode *vp, struct simplelock *inter_lkp, struct proc *p);

DESCRIPTION

     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).

RETURN VALUES

     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.
