|
|
.Sh 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"
|
|
.Sh DESCRIPTION
|
|
.Fn vgone
|
|
and
|
|
.Fn vgonel
|
|
prepare a vnode for reuse by another filesystem.
|
|
The preparation includes the cleaning of all filesystem specific data and
|
|
the removal from its mount point vnode list.
|
|
.Pp
|
|
If the vnode has a
|
|
.Va v_usecount
|
|
of zero, and its
|
|
.Dv VDOOMED
|
|
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 filesystem being unmounted.
|
|
.Pp
|
|
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.
