Great, thanks for testing! Did you happen to look at the performance of your testing? If so, is it comparable/better/worse? FYI, I went ahead and added your Tested-by: to this commit: https://git.kernel.org/cgit/linux/kernel/git/device-mapper/linux-dm.git/commit/?h=for-next&id=e596370123136b37757f4c7d01fb6a6cba26452b And I also staged the entire series in linux-next (for 3.20 at earliest). Still have much more testing to do on these changes but it'll be good to let them soak in linux-next over the holiday break. > The only issue I hit during this test is the one mentioned on > https://lkml.org/lkml/2014/10/29/523 but that's a bug in the e1000 > driver that is not related to multipath. OK, hopefully you'll hear back from the maintainers on that thread soon.
