179 include/linux/sched.h:1479:35: error: field 'arch' has incomplete typeThis comes from 09b09ab71840 ("mm, x86/mm: Make the batched unmap TLB flush API more generic"), backported from e73ad5ff2f76d upstream.
My 10-second analysis suggests that we should backport dcc2dc45f7cf ("sched/headers, mm: Move 'struct tlbflush_unmap_batch' from <linux/sched.h> to <linux/mm_types_task.h>")
Ugh, that's not a "straight" port at all, and will it really solve the problem here? At first glance I don't see how, but I must be missing something...
Eduardo, any ideas here? It's blowing up on your backported patch :(
thanks,
