Subject: mm: eliminate VM_SPECIAL, VMA_SPECIAL_FLAGS
Date: Mon, 14 Sep 2026 15:57:57 +0100
Every user of the VM_SPECIAL or VMA_SPECIAL_FLAGS has now been converted
to predicates which explicitly express what is actually being checked for
rather than the nebulous concept of possessing 'special' VMA flags.
In any case 'special' is not so special a term of art in mm - it includes
VDSO/VVAR mappings, special in the sense of vm_normal_folio() and probably
other cases too.
Therefore make things less special by eliminating these now unused flags.
No functional change intended.

The quilt patch titled
Subject: mm: eliminate VM_SPECIAL, VMA_SPECIAL_FLAGS
has been removed from the -mm tree. Its filename was
mm-eliminate-vm_special-vma_special_flags.patch
This patch was dropped because an updated version will be issued
------------------------------------------------------
From: "Lorenzo Stoakes (ARM)" <ljs@kernel.org>
Subject: mm: eliminate VM_SPECIAL, VMA_SPECIAL_FLAGS
Date: Fri, 09 Oct 2026 19:04:30 +0100
Every user of the VM_SPECIAL or VMA_SPECIAL_FLAGS has now been converted to
predicates which explicitly express what is actually being checked for
rather than the nebulous concept of possessing 'special' VMA flags.
In any case 'special' is not so special a term of art in mm - it includes
VDSO/VVAR mappings, special in the sense of vm_normal_folio() and probably
other cases too.
Therefore make things less special by eliminating these now unused flags.
No functional change intended.
