Subject: [PATCH 5/6] mm: add nommu variant of vm_insert_pages()
Date: Thu, 21 Mar 2024 08:45:00 -0600 [thread overview]
Message-ID: <[email protected]> (raw)
In-Reply-To: <[email protected]>
An identical one exists for vm_insert_page(), add one for
vm_insert_pages() to avoid needing to check for CONFIG_MMU in code using
it.
