Indeed, we have this fix:

commit 6c21811060c03100a32d0acc493df5fb3743b7c8

     fs: aufs: fix a build error for archs which doesn't support 
MUTEX_SPIN_ON_OWNER

     For struct mutex, the member "owner" only exist when either
     DEBUG_MUTEXES or MUTEX_SPIN_ON_OWNER is enabled. The SMP is a necessary
     condition, but not a sufficiency condition for MUTEX_SPIN_ON_OWNER.
     So we would get build error on arch such as mpis due to SMP is
     enabled and both DEBUG_MUTEXES and MUTEX_SPIN_ON_OWNER are disabled.
     Replace the SMP with MUTEX_SPIN_ON_OWNER to fix it.

And it is on the edgerouter branch.

So either the fix isn't complete, or we are building a different config
here, or the revs are wrong.

... and indeed, that isn't part of the patch Kevin sent, so you are building
and old SRCREV.

I'll send a follow up patch shortly.
