That's because I'm a blind idiot and managed to miss the idiocy in
delayed_fput() -  that
	list_splice(&head, &delayed_fput_list);
should've been
	list_splice_init(&delayed_fput_list, &head);

Even more embarrassingly, I've actually screwed up the build scripts
and hadn't discovered until now that I'd been testing without initramfs;
as soon as I'd found that, the bug had promptly reproduced itself.

Anyway, I've pushed the fix into vfs.git#master.  Should propagate
to git.kernel.org in a few (commit 2ae9632 is the branch head)
