Jason, I am trying to figure out what caused a big drop in performance in the rxe driver between v6.5-rc5 and v6.5-rc6. The maximum performance for 'ib_send_bw -F -a' in local loopback mode dropped from about 1.9GB/sec to 1.1GB/sec between these two tags. I have also measured the performance of a 6.5 kernel with the 6.4 rxe driver and 6.4 infiniband/core drivers and that also shows the lower performance so it is not something in the rdma subsystem. (In fact there were no changes in the rxe driver from 6.5-rc5 to 6.5-rc6.) If I type 'git log --oneline v6.5-rc6 ^v6.5-rc5' I get about 360 lines but many of them are merge sets that can contain many patches. Is there a way to list all the patches contained between these two tags? Thanks, Bob
