What are the git commit ids? > Hi Greg, thanks for your prompt response! The story behind these patches is a bit confusing; I'll summarize below. I've submitted 2 patches with fixes to linux-raid in April; if you wanna take a look, they are: https://marc.info/?l=linux-raid&m=155839017427565 https://marc.info/?l=linux-raid&m=155839017827569 After some discussion, it was determined a patchset from Ming Lei fixed the same issues I've reported/fixed, but it was a rework (and depends on the removal of legacy IO path). That said, Song Liu submitted both of my fixes as stable-only patches. I couldn't find a stable archive (and I don't subscribe to that), so I cannot point links here. I just resubmitted both patches, this time CCing you and Sasha. Let me know if there's anything needed - I'd prefer to have them upstream too, but the discussion with Christoph/Ming/Song reached a consensus that it wouldn't make sense to add them and soon after add Ming's patchset, which removes that code. But backporting Ming's series is not really simple/feasible. Thanks, Guilherme > I have no record of these patches in my queue at the moment, sorry.
