 Modified Files:
 	src/sys/sys: param.h proc.h
 
 Log Message:
 struct proc: Move p_pgrp out of p_startcopy/endcopy region.
 
 It cannot be safely copied with the current memcpy logic that logic
 uses happens without holding proc_lock, so we have to copy it
 separately anyway.  Leave a comment emphasizing this aspect of the
 locking rules so we don't have this bug again.
 
 Looks like p_mqueue_cnt may need similar treatment.
 
 As a result of this kernel ABI change, welcome to 11.99.10!
