So I also enabled lockdep to see if it might show a locking problem even
when initcall_debug avoids the race. Unfortunately nothing shows up at
boot, but when I try to use FunctionFS I got the following lockdep
splat, which then triggered a warning and then finally an oops all in
succession.
The core lockdep parts are below, and the full log is attached. (Sorry
its cropped at 80 lines, I wasn't logging my screen session at the time,
so its all copy-pasted. Let me know if you'd need me to recreate the
problem.)
