Its filename is mm-make-map_kernel_pages_-internal-and-unexported.patch This patch will shortly appear at https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patches/mm-make-map_kernel_pages_-internal-and-unexported.patch This patch will later appear in the mm-unstable branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next via various branches at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm and is updated there most days ------------------------------------------------------ From: "Lorenzo Stoakes (ARM)" Subject: mm: make map_kernel_pages_[prepare,complete] internal and unexported Date: Tue, 13 Oct 2026 16:04:45 +0100 There's no reason to export the symbols for these functions which are only called from internal mm logic, additionally there's no reason for them to be declared in mm.h. This patch therefore removes the exports and moves the declarations to mm/internal.h. No functional change intended.
