NAME

vgone , vgonel - prepare a vnode for reuse

SYNOPSIS

In sys/param.h In sys/vnode.h Ft void Fn vgone struct vnode *vp Ft void Fn vgonel struct vnode *vp struct thread *td

DESCRIPTION

Fn vgone and Fn vgonel prepare a vnode for reuse by another file system. The preparation includes the cleaning of all file system specific data and the removal from its mount point vnode list.

If the vnode has a v_usecount of zero, and its VI_DOOMED flag is not set, it is moved to the head of the free list as in most cases the vnode is about to be reused, or its file system is being unmounted.

The difference between Fn vgone and Fn vgonel is that Fn vgone locks the vnode interlock and then calls Fn vgonel while Fn vgonel expects the interlock to already be locked.
