After compiling 2.6.0-test7-mm1, I get the following error after installing the
modules:

if [ -r System.map ]; then /sbin/depmod -ae -F System.map  2.6.0-test7-mm1; fi
WARNING: /lib/modules/2.6.0-test7-mm1/kernel/fs/ext2/ext2.ko needs unknown symbol
__blockdev_direct_IO

I checked the filesystem code and the function __blockdev_direct_IO is defined
at fs/direct-io.c, line 1020. However, the EXPORT_SYMBOL() definition uses
"blockdev_direct_IO", not "__blockdev_direct_IO". Grepping the include/linux
directory shows inline definitions for various wrappers for __blockdev_direct_IO,
including "blockdev_direct_IO", in include/linux/fs.h at line 1355. Yet depmod
can't seem to find it for the ext2 module.

Does this have anything to do with Jens Axboe's IDE write barrier/JBD write
barrier work?

I don't see any patches in your ChangeLog which could have caused this, since
it didn't happen under 2.6.0-test7 or 2.6.0-test6-mm4. Just from looking at the

"might_sleep-vs-jiffies-wrap.patch" pops to mind, it probably just didn't
get reported in earlier kernels because starting with INITIAL_JIFFIES!=0
broke the rate limiting logic (sorry for that)

Well, I don't use the IEEE1394 drivers (yet), so like I said, it's non-fatal. Are
there any other debugging options I can enable that would help pinpoint this
(i.e frame pointers?)

highlevel_add_host() does read_lock() and then proceeds to do things like
starting kernel threads under that lock.  The locking is pretty broken
in there :(

No, highlevel_add_host() itself doesn't start any threads. But it does
pass around data that needs to be locked from changes, and one of the
handlers happens to start a thread, and other things allocate memory
(such as this case).

It's ugly, and I've been trying to clean it up. This case can be fixed
quickly with a simple check in hpsb_create_hostinfo() to pass GFP_ATOMIC
to kmalloc.

My problem right now, is I don't use any architectures that support
preempt, so I don't see a lot of these problems, like I catch with
CONFIG_SMP.

nodemgr_add_host() looks like the hard one.  Maybe make hl_drivers_lock a
sleeping lock?

Anton had a ppc64 patch which implemented the preempt_count beancounting
without actually implementing premption.  So might_sleep() does the right
thing.

Problem is, things like bus resets happen in interrupt, and while I can
push off some things to occur in the nodemgr thread, a lot of other
stuff has to happen in the interrupt, and they require the same lock.

It's all a matter of just tossing out my todo list for a good week and
redoing all of this logic from the ground up. I have high hopes this
will happen in the next few weeks, but I'm not signing any contracts to
hold me to it :)

I might have to dig that out and try to make use of it. Thanks for the
pointer.

Here is the patch with the ppc64 bits in it. (I already have
might_sleep() littered in asm-ppc64/semaphore.h and asm-ppc64/uaccess.h)

Its a bit old but it seems to dump valid warnings.

I was looking briefly at this too, and as you say, the problem is that 
some things have to happen in interrupt, others happen in process 
context.  I've attached a patch that implements one way to fix it: 
double book-keeping - we maintain two lists of the highlevel drivers, 
one protected by a semaphore another protected by the rw spinlock. The 
lists are identical, except between the two list_add_tail()'s (and the 
two list_del()'s), but that doesn't allow any harmful race conditions.

A more radical approach would be to split the highlevel interface into 
two interfaces add_host() + remove_host() in a hpsb_host_notification 
interface and the rest in another interface.  The driver would have to 
register both interfaces if it needs them. Some drivers only use 
add_host() and remove_host(), so they could register only the 
hpsb_host_notification interface.

best regards,
Kristian

Actually I'm leaning toward getting rid of our internal locking and
reference counting and relying heavily on the device model's reference
counting and such. Take some of the work load off of our code.

Each host already has a device associated with it, so it just requires a
revamp of some internals.

JFYI, this bug also appears under 2.6.0-test8:

Since I don't use the OHCI1394 drivers yet, I can't really offer any assistance,
except to test patches that make the debug message go away.

As would be expected considering I'm holding off changes to let 2.6
focus on core issues. The "bug" is pretty much harmless as-is, even if
noisy, and wont show up under normal compiles with debugging disables.

Plus, my fix is a little more than trivial, so I'm keeping it for 2.6.1.

Oh great, let's wait for the "little more than trivial" bug fixes until
after it's released....

I understand that you're busy, and your schedule may force you to wait until
after 2.6.0, but 2.6-test is to help get the bugs out of a release, and this
is a bug fix so it should be accepted...

Obviously you haven't been reading Linus' posts about what he'll accept
into 2.6.0-test before 2.6.0 is final. He wont take my patches, and
rightfully so.

This isn't a matter of my choice, it's a matter of timing. Get over it,
and download the latest stuff from linux1394.org if you need it that
badly. Here's a hint:

# cd /usr/src/linux-2.6.0-test9
# rm -rf drivers/ieee1394
# wget -o trunk.tar.gz http://www.linux1394.org/viewcvs/trunk/trunk.tar.gz?tarball=1
# tar zxf trunk.tar.gz 
# mv trunk drivers/ieee1394
# rm -f trunk.tar.gz

It doesn't get any simpler than that.

I was thinking of simply suppressing all these early warnings:

--- 25/kernel/sched.c~might_sleep-early-bogons	Wed Oct 15 14:29:21 2003
+++ 25-akpm/kernel/sched.c	Wed Oct 15 14:31:21 2003
@@ -2855,7 +2855,7 @@ void __might_sleep(char *file, int line)
 #if defined(in_atomic)
 	static unsigned long prev_jiffy;	/* ratelimiting */
 
-	if (in_atomic() || irqs_disabled()) {
+	if (system_running && in_atomic() || irqs_disabled()) {
 		if (time_before(jiffies, prev_jiffy + HZ) && prev_jiffy)
 			return;
 		prev_jiffy = jiffies;


But really we shouldn't do that because it is possible that an early
accidental enabling of interrupts can lock the box.  That happens on ppc64
for example.

We should fix them up.
