We are at the end of the dev cycle, and as nothing major has come up I'll push this toward linux-next to get some coverage and decide next week what goes this cycle. v3 changes: - Keep NEED_WRITE_FAULT and NEED_FAULT separate (CH) - Use CH's vesion of hmm_can_fault and drop the inline v2: https://lore.kernel.org/r/20200324011457.2817-1-jgg@ziepe.ca v1: https://lore.kernel.org/r/20200320164905.21722-1-jgg@ziepe.ca Thanks to everyone who looked on this, Jason Jason Gunthorpe (9): mm/hmm: remove pgmap checking for devmap pages mm/hmm: return the fault type from hmm_pte_need_fault() mm/hmm: remove unused code and tidy comments mm/hmm: remove HMM_FAULT_SNAPSHOT mm/hmm: remove the CONFIG_TRANSPARENT_HUGEPAGE #ifdef mm/hmm: use device_private_entry_to_pfn() mm/hmm: do not unconditionally set pfns when returning EBUSY mm/hmm: do not set pfns when returning an error code mm/hmm: return error for non-vma snapshots Documentation/vm/hmm.rst | 12 +- drivers/gpu/drm/amd/amdgpu/amdgpu_ttm.c | 2 +- drivers/gpu/drm/nouveau/nouveau_svm.c | 2 +- include/linux/hmm.h | 109 +-------- mm/hmm.c | 307 +++++++++--------------- 5 files changed, 128 insertions(+), 304 deletions(-)
