Subject: [PATCH v9 0/3] mm/hmm/test: add self tests for HMM
This series adds basic self tests for HMM and are intended for Jason
Gunthorpe's rdma tree since I believe he is planning to make some HMM
related changes that this can help test.
Changes v8 -> v9:
Rebased to linux-5.7.0-rc1.
Moved include/uapi/linux/test_hmm.h to lib/test_hmm_uapi.h
Added calls to release_mem_region() to free device private addresses
Applied Jason's suggested changes for v8.
Added a check for no VMA read access before migrating to device private
memory.
Changes v7 -> v8:
Rebased to Jason's rdma/hmm tree, plus Jason's 6 patch series
"Small hmm_range_fault() cleanups".
Applied a number of changes from Jason's comments.
Changes v6 -> v7:
Rebased to linux-5.6.0-rc6
Reverted back to just using mmu_interval_notifier_insert() and making
this series only introduce HMM self tests.
Changes v5 -> v6:
Rebased to linux-5.5.0-rc6
Refactored mmu interval notifier patches
Converted nouveau to use the new mmu interval notifier API
Changes v4 -> v5:
Added mmu interval notifier insert/remove/update callable from the
invalidate() callback
Updated HMM tests to use the new core interval notifier API
Changes v1 -> v4:
