The nouveau driver was tested before and after this patchset and it +builds and works on both case so there is no merging issue [2]. + +If this get merge in 5.1 the plans is to merge the HMM to ODP in 5.2 or +5.3 if testing shows any issues (so far no issues has been found with +limited testing but Mellanox will running heavier testing for longer +time). + +To avoid spamming mm i would like to not cc mm on ODP or nouveau patches, +however if people prefer to see those on mm mailing list then i can keep +it cced. + +[1] https://cgit.freedesktop.org/~glisse/linux/log/?h=odp-hmm +[2] https://cgit.freedesktop.org/~glisse/linux/log/?h=hmm-for-5.1 + +Cc: Andrew Morton +Cc: Felix Kuehling +Cc: Christian König +Cc: Ralph Campbell +Cc: John Hubbard +Cc: Jason Gunthorpe +Cc: Dan Williams -- cgit v1.2.3
