This time the focus # is on the driver pattern to use mmu notifiers to monitor a VA range. # This code is lifted out of many drivers and hmm_mirror directly into # the mmu_notifier core and written using the best ideas from all the # driver implementations. # # This removes many bugs from the drivers and has a very pleasing # diffstat. More drivers can still be converted, but that is for another # cycle. # # - A shared branch with RDMA reworking the RDMA ODP implementation # # - New mmu_interval_notifier API. This is focused on the use case of # monitoring a VA and simplifies the process for drivers # # - A common seq-count locking scheme built into the # mmu_interval_notifier API usable by drivers that call # get_user_pages() or hmm_range_fault() with the VA range # # - Conversion of mlx5 ODP, hfi1, radeon, nouveau, AMD GPU, and Xen # GntDev drivers to the new API. This deletes a lot of wonky driver # code. # # - Two improvements for hmm_range_fault(), from testing done by Ralph" # # * tag 'for-linus-hmm' of
