Well, as demonstrated by ru's commit (thanks ru!).. I had not tested DEVICE_POLLING... But this afternoon I did some testing, and did not have any troubles... The only problems w/ netperf was that the *RR* tests were a bit slow, but this is to be expected due to DEVICE_POLLING.. But as I mentioned, the re driver was originally based on the rl, so I doubt there'll be much trouble since rl's locking has been in the tree for quite a while longer... -- John-Mark Gurney Voice: +1 415 225 5579 "All that I will do, has been done, All that I have, has not."Received on Sat Sep 04 2004 - 21:57:00 UTC
