Subject: mm: add nommu variant of vm_insert_pages()
X-Git-Tag: for-6.10/io_uring-20240511~52
X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=62346c6cb28b043f2a6e95337d9081ec0b37b5f5;p=linux-block.git

mm: add nommu variant of vm_insert_pages()

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.
