Subject: [PATCH v2 0/6] Account page tables at all levels
Date: Fri, 3 Jan 2025 18:44:09 +0000 [thread overview]
Message-ID: <20250103184415.2744423-1-kevin.brodsky@arm.com> (raw)
v1: https://lore.kernel.org/linux-mm/20241219164425.2277022-1-kevin.brodsky@arm.com/
This series should be considered in conjunction with Qi's series [1].
Together, they ensure that page table ctor/dtor are called at all levels
(PTE to PGD) and all architectures, where page tables are regular pages.
Besides the improvement in accounting and general cleanup, this also
create a single place where construction/destruction hooks can be called
for all page tables, namely the now-generic pagetable_dtor() introduced
by Qi, and __pagetable_ctor() introduced in this series.
v2 is essentially v1 rebased on top of mm-unstable, which includes Qi's
v4 series. A number of patches from v1 were dropped:
* v1 patch 4 is superseded by patch 6 in Qi's series.
* v1 patch 5 and 6 moved to Qi's series from v3 onwards.
* v1 patch 7 is superseded by patch 4 in Qi's series.
Changes from v1 in the remaining patches:
* Patch 1 only introduces __pagetable_ctor() as there is now a single
generic pagetable_dtor().
* Patch 3 and 6: in arch/m68k/mm/motorola.c, free_pointer_table() can
now unconditionally call pagetable_dtor() since it is the same for all
levels.
* Patch 6 just uses pagetable_dtor() instead of introducing
pagetable_pgd_dtor().
* Added Dave Hansen's Acked-by to all patches.
- Kevin
