VOP_INACTIVE(9) FreeBSD Kernel Developer's Manual VOP_INACTIVE(9)

VOP_INACTIVE, VOP_RECLAIM
reclaim file system resources for a vnode

#include <sys/param.h>
#include <sys/vnode.h>
int
VOP_INACTIVE(struct vnode *vp, struct thread *td);
int
VOP_RECLAIM(struct vnode *vp, struct thread *td);

The arguments are:
vp
The vnode being reclaimed.
VOP_INACTIVE() is called when the kernel is no longer using the vnode. This may be because the reference count reaches zero or it may be that the file system is being forcibly unmounted while there are open files. It can be used to reclaim space for ‘open but deleted’ files.
VOP_RECLAIM() is called when a vnode is being reused for a different file system. Any file system specific resources associated with the vnode should be freed.

For both VOP_INACTIVE() and VOP_RECLAIM(), the vp will be exclusively locked on entry, and must be left exclusively locked on return.
