https://origsvn.digium.com/svn/asterisk/branches/1.4 ........ r105116 | russell | 2008-02-28 16:23:05 -0600 (Thu, 28 Feb 2008) | 8 lines Fix a bug in the lock tracking code that was discovered by mmichelson. The issue is that if the lock history array was full, then the functions to mark a lock as acquired or not would adjust the stats for whatever lock is at the end of the array, which may not be itself. So, do a sanity check to make sure that we're updating lock info for the proper lock. (This explains the bizarre stats on lock #63 in BE-396, thanks Mark!) ........ git-svn-id: http://svn.digium.com/svn/asterisk/trunk@105144 f38db490-d61c-443f-a65b-d21fe96a405b
