Re: [RFC PATCH 2.6.17-mm1 4/3] ieee1394: convert ieee1394_transactions from semaphores to waitqueue

I wrote:

There were 63 instances of counting semaphores used for each hpsb_host.
All of them are now replaced by a single wait_queue.

After this and patch "ieee1394: dv1394: sem2mutex conversion", the following semaphores remain in the ieee1394 subsystem:

highlevel.c:  hl_drivers_sem    (RW semaphore)
nodemgr.c:    subsys.rwsem      (driver core's RW semaphores)
raw1394.c:    fi->complete_sem  (completion semaphore)
