Subject: [PATCH 0/2] mm/migrate: optimize migrate_vma_setup() for holes
Date: Thu, 9 Jul 2020 09:57:09 -0700 [thread overview]
Message-ID: <20200709165711.26584-1-rcampbell@nvidia.com> (raw)
A simple optimization for migrate_vma_*() when the source vma is not an
anonymous vma and a new test case to exercise it.
This is based on linux-mm and is for Andrew Morton's tree.
