It is called after VOP_RECLAIM is called by vgonel(), after fs-specific data are destroyed. So, on the one hand, vop can only operate on struct vnode proper, on the other hand, the actions performed by vop_advlockpurge implementation can be done by vop_reclaim as well.
Could you, please, give some details on the supposed use of the vop ?
