Subject[PATCH v8 0/3] mm/hmm/test: add self tests for HMM
Date
This series adds basic self tests for HMM and are intended for Jason
Gunthorpe's rdma tree which has a number of HMM patches applied.

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:
