Re: spin_trylock_wr() patch

[Matthew Dillon <dillon@xxxxxxxxxxxxxxxxxxxx>]

:I think there is another issue in the loop that tries to clear the
:shared cached bits.

:We fail to get the lock if some CPU has its bit set and is owning
:*another* spinlock (or none).  It should presumably fail if still
:holding the lock we're trying to get.
