Its filename was fs-proc-task_mmu-do-not-warn-on-seeing-non-migration-pmd-entry.patch This patch was dropped because an updated version will be issued ------------------------------------------------------ From: Dev Jain Subject: fs/proc/task_mmu: do not warn on seeing non-migration pmd entry Date: Sat, 30 May 2026 08:54:11 +0000 Patch series "mm/hmm: A fix and a selftest", v2. Patch 1 fixes a stale warning present from the time when only migration softleaf entries were supported at the PMD level. Patch 2 adds some code into hmm-tests.c which exercises the pagemap path for PMD device-private entries. This patch (of 2): pagemap_pmd_range_thp() warns if a non-present PMD is not a migration entry. This became false once device-private entries at the PMD level were added. Therefore, remove the stale migration-only assertion.
