I was actually working on some selftests for this before I hit a weird bug during some of my testing, which took precedence over that. I was planning on sending a separate series for the testing. One of the pain points was that selftests helpers were set up for PMDs, but I think Baolin just cleaned that up in his khugepaged mTHP shmem series (still need to review). So it should be a lot easier to implement now. > > > V10 Changes: > > I'll add this to mm-new, thanks. I'll suppress the usual emails. Thank you :) -- Nico >
