Subject: [PATCH v3 7/8] mm: add generic type support to migrate_vma helpers
Date: Thu, 17 Jun 2021 10:17:04 -0500 [thread overview]
Message-ID: <20210617151705.15367-8-alex.sierra@amd.com> (raw)
In-Reply-To: <20210617151705.15367-1-alex.sierra@amd.com>
Device generic type case added for migrate_vma_pages and
migrate_vma_check_page helpers.
Both, generic and private device types have the same
conditions to decide to migrate pages from/to device
memory.
