[openib-general] [RFC] [PATCH 8/8] rdma_ucm 2.6.20: add userspace support for rdma_cm

[Steve Wise]

FYI:  Once the ucma gets into roland's git tree, I'll base the chelsio
drivers against the appropriate branch (for-2.6.20?) and test this whole
thing with the chelsio driver, user and kernel.


Steve.
