Yup.The oops scrolled off my screen, but the call chain was:

init_sel_fs -> kernel_mount_data -> vfs_kern_mount -> mount_fs ->
sel_mount -> mount_single -> (scrolled off)

and then the actual oops happens in d_alloc+0x17, which is
"parent->d_sb", so parent was NULL or something (the register state
also scrolled off, and I didn't check the fault address, so it could
have been some other invalid pointer too).
