Subject: [PATCH 01/10] mm: add nommu variant of vm_insert_pages()
Date: Wed, 27 Mar 2024 13:13:36 -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.
