If "modprobe ohci1394" was quickly followed by "modprobe -r ohci1394",
say with 1 second pause in between, the modprobe -r got stuck in
uninterruptible sleep in kthread_stop. At the same time the knodemgrd
slept uninterruptibly in bus_rescan_devices_helper. That's because
driver_detach took the semaphore of the PCI device and
bus_rescan_devices_helper wanted to take the semaphore of the FireWire
host device's parent, which is the same semaphore. This was a regression
since Linux 2.6.16, commit bf74ad5bc4,
"Hold the device's parent's lock during probe and remove".
The fix (or workaround) adds a dummy driver to the hpsb_host device. Now
bus_rescan_devices_helper won't scan the host device anymore. This
doesn't hurt since we have no drivers which will bind to these devices
and it is unlikely that there will ever be such a driver. The dummy
driver is befittingly presented as a representation of ieee1394 itself.

The queue depth can be read from /sys/bus/scsi/devices/*/queue_depth,
so don't log it. And the hint about speed improvements is misleading,
at least under current kernels. If serialization is switched off, read
performance is typically increased by less than 10%. (I did not test
write performance recently.) On the other hand, serialize_io=0 is not
yet safe due to some implementation issues that are not trivial to fix.

- The list "struct class.children" is supposed to be protected by
class.sem, not by class.subsys.rwsem.
- nodemgr_remove_uds() iterated over nodemgr_ud_class.children without
proper protection. This was never observed as a bug since the code
is usually only accessed by knodemgrd. All knodemgrds are currently
globally serialized. But userspace can trigger this code too by
writing to /sys/bus/ieee1394/destroy_node.
- Clean up access to the FireWire bus type's subsys.rwsem: Access it
uniformly via ieee1394_bus_type. Shrink rwsem protected regions
where possible. Expand them where necessary. The latter wasn't a
problem so far because knodemgr is globally serialized.
This should harden the interaction of ieee1394 with sysfs and lay ground
for deserialized operation of multiple knodemgrds and for implementation
of subthreads for parallelized scanning and probing.

video1394 does not need to take the BKL. The data structures shared between

I did a quick shot on what I described and the appended patch
does the first thing needed for working suspend/resume
in ohci1394 which is HW de- and re-initialisation.
It works with suspend2disk on my Ricoh R5C552 IEEE 1394 Controller
with the 2.6.17 kernel to the extent that if I call dvgrab --interactive
after suspend2disk without unloading ohci1394, it does not lock up
dvgrab with 100% CPU but properly connects to the camera, given
that I first unplug and plug the camera after coming back from
suspend.
I guess that could be fixed by forcing a bus reset in the resume
function.
I cannot test suspend to RAM here at the moment and should
follow the guidelines in Documentation/power/pci.txt also,
so this is rather a quick report than a finished patch and
there are some rough edges:
However, with this patch, I have to unload at least some in-kernel
users of ohci1394 like dv1394 or video1394 before suspending.
Not doing that caused an Oops and a bad tasklet error, probably from
not handling ISO tasklets during suspend/resume properly.
Maybe these can be temporarily cleared or unregistered and
re-registered for suspend/resume with help from the other
layers or from the highlevel 1394 core, but I do not really
know what these do.
But this patch provides a useful base to start from and is
already of much help for people which do not need dv1394
and video1394 or can unload them at least during suspend.
I cannot test function with sbp2 at the moment, but raw1394
seems to work fine.

This allows workqueue users to run just their own pending work, rather
than wait for the whole workqueue to finish running. This solves the
deadlock with networking libphy that was due to other workqueue entries
possibly needing a lock that was held by the routine that wanted to
flush its own work.
It's not wonderful: if you absolutely need to synchronize with the work
function having been executed, any user strictly speaking should have
its own completion tracking logic, since when we run things explicitly
by hand, the generic workqueue layer can no longer help us synchronize.
Also, this is strictly only usable for work that has been scheduled
without any delayed timers. You can not mix the new interface with
schedule_delayed_work().
But it's better than what we had currently.

The IPMI BT subdriver has been patched to survive "long busy" timeouts seen
during firmware upgrades and resets. The patch never returns the HOSED state,
synthesizes response messages with meaningful completion codes, and recovers
gracefully when the hardware finishes the long busy. The subdriver now issues
a "Get BT Capabilities" command and properly uses those results. More
informative completion codes are returned on error from transaction starts;
this logic was propogated to the KCS and SMIC subdrivers. Finally, indent and
other style quirks were normalized.

This creates a new RTC-framework driver for the RTC/calendar module found
in various OMAP1 chips. (OMAP2 and OMAP3 use external RTCs, like those in
TI's multifunction PM companion chips.) It's been in the Linux-OMAP tree
for several months now, and other trees before that, so it's quite stable.
The most notable issue is that the OMAP IRQ code doesn't yet support the
RTC IRQ as a wakeup event. Once that's fixed, a patch will be needed.

When CONFIG_HOTPLUG=n, agp_amd64_resume() calls nforce3_agp_init(), which is
__devinit == __init, so has been discarded and is not usable for resume.

When CONFIG_HOTPLUG=n, parport_pc calls some __devinit == __init code that
could be discarded. These calls are made from parport_irq_probe(), which is
called from parport_pc_probe_port(), which is an exported symbol, so the calls
could (possibly) happen after init time.

There was lots of #ifdef noise in the kernel due to hotcpu_notifier(fn,
prio) not correctly marking 'fn' as used in the !HOTPLUG_CPU case, and thus
generating compiler warnings of unused symbols, hence forcing people to add
#ifdefs.
the compiler can skip truly unused functions just fine:
