History
Greg Lehey c4d4f4147d Add a new debug flag, DEBUG_LOCKREQS, which logs only lock requests. 
Use this instead of DEBUG_LASTREQS to decide whether to log lock
requests.

MFS:

vinumlock: Catch a potential race condition where one process is
           waiting for a lock, and between the time it is woken and
           it retries the lock, another process gets it and places it
           in the first entry in the table.

           This problem has not been observed, but it's possible, and
           it's easy enough to fix.

Submitted by:   tegge

vinumunlock: Catch a real bug capable of hanging a system.  When
             releasing a lock, vinumunlock() called wakeup_one.  This
             caused wakeups to sometimes get lost.  After due
             consideration, we think that this is due to the fact that
             you can't guarantee that some other process is also
             waiting on the same address.  This makes wakeup_one a
             very dangerous function to use.
