The quilt patch titled
Subject: ksm: convert ksm_mm_slot.link to ksm_mm_slot.hash
has been removed from the -mm tree. Its filename was
ksm-convert-ksm_mm_slotlink-to-ksm_mm_slothash.patch
This patch was dropped because it was merged into the mm-stable branch
of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Subject: ksm: convert ksm_mm_slot.link to ksm_mm_slot.hash
Date: Wed, 31 Aug 2022 11:19:50 +0800
In order to use common struct mm_slot, convert ksm_mm_slot.link to
ksm_mm_slot.hash in advance, no functional change.
