Possible fix - patch simplifies completion counting and avoids races
Hi Lukas:
This patch has successfully passed an initial round of tests which 2.6.38-rc*
kernels have never passed. It seemed appropriate to simplify the way
outstanding completions were being accounted for to avoid the races, and the
code ought to be just a little more efficient on a SMP/NUMA box as well. At
any rate, it's a stab at it - I'd appreciate any comments you might have. I'll
put it through a weekend's worth of test runs next.
Thanks!
Eric
