Subject: [PATCH] arm: struct semaphore.sleepers initialization
Date: Fri, 28 Oct 2005 23:26:35 -0400 [thread overview]
Message-ID: <20051029032635.GA1870@krypton> (raw)
No one may sleep on us until we've been down()'d. So on allocation,
initialize `sleepers' to 0, just like everyone else (including arm26).
