The following patches clean up and convert API usages in
ieee1394/nodemgr.c. Parts of this patch series supersede the previously
posted variants of "[PATCH] kthread conversion: convert ieee1394 from
kernel_thread".
1/6 ieee1394: nodemgr: remove unnecessary includes
2/6 ieee1394: do not spawn a kernel_thread for user-initiated bus rescan
3/6 ieee1394: make module parameter ignore_drivers writable
4/6 ieee1394: nodemgr: switch to kthread API
5/6 ieee1394: nodemgr: replace reset semaphore
6/6 ieee1394: convert nodemgr_serialize semaphore to mutex

In case someone actually puts these patches to test and finds a lockup
or something more serious, please check if it isn't this older bug:
http://bugzilla.kernel.org/show_bug.cgi?id=6706
Two things which I could not test are behaviour on actual SMP machines
and the try_to_freeze() business.
Patch 3/6 is not an API conversion but is loosely related to patch 2/6.
After this patchset, all usages of the kernel_thread API are removed
from the ieee1394 subsystem. Two usages of semaphores are replaced.
The following semaphores are still remaining in drivers/ieee1394:
dv1394.c: video->sem (simple mutex-type semaphore)
highlevel.c: hl_drivers_sem (RW semaphore)
ieee1394_transactions.c: tp->count (counting semaphore)
nodemgr.c: subsys.rwsem (driver core's RW semaphores)
raw1394.c: fi->complete_sem (completion semaphore)
