Its filename was mm-memory-failure-convert-try_memory_failure_hugetlb-to-folios.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 ------------------------------------------------------ From: Sidhartha Kumar Subject: mm/memory-failure: convert try_memory_failure_hugetlb() to folios Date: Thu, 12 Jan 2023 14:46:02 -0600 Use a struct folio rather than a head page in try_memory_failure_hugetlb. This converts one user of SetHPageMigratable to the folio equivalent.
