[merged mm-hotfixes-stable] mm-folio-export_symbol_for_kvmlru_cache_drain_for_folio.patch removed from -mm tree

[Andrew Morton]

The quilt patch titled
     Subject: mm/folio: EXPORT_SYMBOL_FOR_KVM(lru_cache_drain_for_folio)
has been removed from the -mm tree.  Its filename was
     mm-folio-export_symbol_for_kvmlru_cache_drain_for_folio.patch

This patch was dropped because it was merged into the mm-hotfixes-stable branch
of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Subject: mm/folio: EXPORT_SYMBOL_FOR_KVM(lru_cache_drain_for_folio)
Date: Tue, 1 Sep 2026 20:38:40 -0700 (PDT)

To simplify independent development in the KVM and MM subsystems, now
export to KVM the lru_cache_drain_for_folio() which MM added in 7.3-rc1.

Thanks all!

Would like to check on branch management for mm-hotfixes-stable: Does
this patch being on mm-hotfixes-stable now (7.3-rc2) mean that this will
make it to 7.3-rc3?

Unless it gets yanked last minute, which is unlikely given that it is in -stable :)
