MAINTAINERS: add HMM selftests (2020-05-19 16:48:31 -0300)
----------------------------------------------------------------
hmm related patches for 5.8
This series adds a selftest for hmm_range_fault() and several of the
DEVICE_PRIVATE migration related actions, and another simplification for
hmm_range_fault()'s API.
- Simplify hmm_range_fault() with a simpler return code, no
HMM_PFN_SPECIAL, and no customizable output PFN format
- Add a selftest for hmm_range_fault() and DEVICE_PRIVATE related
functionality
----------------------------------------------------------------
