Subject: [PATCH 0/2] mm/hmm: two bug fixes for hmm_range_fault()
Date: Fri, 23 Aug 2019 15:17:51 -0700 [thread overview]
Message-ID: <20190823221753.2514-1-rcampbell@nvidia.com> (raw)
I have been working on converting Jerome's hmm_dummy driver and self
tests into a stand-alone set of tests to be included in
tools/testing/selftests/vm and came across these two bug fixes in the
process. The tests aren't quite ready to be posted as a patch.
I'm posting the fixes now since I thought they shouldn't wait.
They should probably have a fixes line but with all the HMM changes,
I wasn't sure exactly which commit to use.
These are based on top of Jason's latest hmm branch.
