I'll drop the old patch from core.git. Should be gone later today. Thanks. This patch is superseded by v3, the complete patch rebuilt from the v2 in shmem-7.5.misc with this fix folded in. It fixes the stack frame warning reported at https://lore.kernel.org/oe-kbuild-all/202611112032.TMyPU6Rm-lkp@intel.com/ v3: https://lore.kernel.org/r/20261112-bug-mm-shmem-undo-batch-v3-1-212db8c24058@linux.dev
