Subject: mm/page_alloc: apply per-task GFP context in bulk allocator
Date: Mon, 14 Sep 2026 10:45:55 +0800

alloc_pages_bulk_noprof() does not call current_gfp_context(), so per-task
scoped allocation constraints (PF_MEMALLOC_NOIO, PF_MEMALLOC_NOFS,
PF_MEMALLOC_PIN) are not applied on the bulk fast path.

The most direct consequence is PF_MEMALLOC_PIN: without clearing
__GFP_MOVABLE, prepare_alloc_pages() selects MIGRATE_MOVABLE for the PCP
list, and a task under memalloc_pin_save() receives movable pages from the
bulk allocator.
