IMHO the problem is that aufs provides an incomplete definition of
pr_fmt. Either it should define AUFS_NAME on the commandline, too, or
should define pr_fmt in an aufs header (or a .c file) #included after
all other headers and only when AUFS_NAME is defined, too.
The ugly thing about aufs' pr_fmt being already there when ack_bad_irq
is defined is, that the message printed by the pr_crit suddenly looks
aufs specific which it clearly isn't. So it should better make sure that
the definition isn't available to ack_bad_irq.
Best regards
