Collective resource limits status report #5

[Gabor Kovesdan]

Since last report, I've resolved the problems that caused kernel panic. 
The linked list handling now seems to be ok, I've checked it many times 
but somehow still there's a bug somewhere. I store an entry there but 
later the job isn't found. I've also added some Robert Watson locking 
(see rwlock(9), last line :) to check if that helps but it caused 
another kernel panics, so this is commented out at the moment. Now, I'm 
working on resolving the locking problem and making the lists actually 
work. I might try debugging with adding some temporary syscalls to 
access internal kernel structures or printing out something with a 
sysctl (this was pgj's idea) so that I can figure out what's going 
wrong. If you have a better idea or you find something strange in the 
patch, please let me know.

Another issue, I've tried to merge my work into p4 but I got strange 
problems. I wrote to soc-admins@ and perforce-admin@ regarding this, I 
hope I can also figure it out soon. For the meantime, I provide a full 
patch, I think it's still easy to read because the main part of the code 
resides in sys/kern/kern_jobs.c.
