md seems to work stable with the resulting tree, but it looks there is a performance regression in the block layer not related to the md issue. If I run a small block IOPS test on a block device created by ib_srp (NOOP scheduler) I see about 11% less IOPS than with 2.6.38.3 (155.000 IOPS with 2.6.38.3 and 140.000 IOPS with 2.6.39-rc3+).
