That's not what we're seeing. We have hardware that does DMA over the network (much like the Infiniband stuff), and we have a testcase that fails if get_user_pages() is used, but not if mlock() is used.


If you don't share your testcase it's unlikely to be fixed.

As I said, the testcase only works with our hardware, and it's also very large. It's one small test that's part of a huge test suite. It takes a couple hours just to install the damn thing.

We want to produce a simpler test case that demonstrates the problem in an easy-to-understand manner, but we don't have time to do that now.
