Log:
Merge kern_acct.c:1.73 from HEAD to RELENG_5:
date: 2005/01/08 04:45:57; author: rwatson; state: Exp; lines: +12 -1
In acct_process(), do a lockless read of acctvp to see if it's NULL
before deciding to do more expensive locking to account for process
exit. This acceptable minor race avoids two mutex operations in
that highly common case of accounting not being enabled.
