Ah, just a couple more things:

* make with W=1 complains about missing prototypes:

net/9p/trans_fd.c:1155:5: warning: no previous prototype for ‘p9_trans_fd_init’ [-Wmissing-prototypes]
 1155 | int p9_trans_fd_init(void)
      |     ^~~~~~~~~~~~~~~~
net/9p/trans_fd.c:1164:6: warning: no previous prototype for ‘p9_trans_fd_exit’ [-Wmissing-prototypes]
 1164 | void p9_trans_fd_exit(void)
      |      ^~~~~~~~~~~~~~~~


* This actually break the 'no trans=tcp' specified case when no extra
module is loaded, but I'm not sure how impactful that is.
See v9fs_get_default_trans(), they iterate through loaded transports
(through register_trans()), we might want to bake in a list that
additionally tries to load modules if no module is loaded at all
(in my opinion virtio makes sense before tcp, then fd, unix, xen, rdma?)

Well, that can probably come later.
