        src/sys/miscfs/genfs: layer_extern.h layer_vnops.c
        src/sys/miscfs/nullfs: null_vnops.c
        src/sys/miscfs/overlay: overlay_vnops.c
        src/sys/miscfs/umapfs: umap_vnops.c
        src/tests/fs/ptyfs: t_nullpts.c

Log Message:
Add layer_revoke() that adjusts the lower vnode use count to be at least as
high as the upper vnode count before passing down the VOP_REVOKE().

This way vclean() check for active (vp->v_usecount > 1) vnodes gets it right.

Should fix PR kern/43456.
