Subject: adding lockdep support to the Blackfin arch
Date: Mon, 8 Jun 2009 19:28:19 -0400 [thread overview]
Message-ID: <8bd0f97a0906081628o7d30e05ld961c00a690c140d@mail.gmail.com> (raw)
ive been extending the Blackfin arch recently to support lockdep.
since i also had to implement irqflags/stacktrace as well, i wouldnt
be surprised if this issue is nested in there, plus this is a no-mmu
system.
at any rate, when i boot up a Blackfin system with PROVE_LOCKING
enabled, i end up with this warning:
Badness at kernel/fork.c:988
which correlates to this in copy_process():
DEBUG_LOCKS_WARN_ON(!p->hardirqs_enabled);
btw, in order to get this to work in the first place, i had to extend
