The quilt patch titled Subject: mm: vmalloc: use trace_alloc_vmap_area event has been removed from the -mm tree. Its filename was mm-vmalloc-use-trace_alloc_vmap_area-event.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: "Uladzislau Rezki (Sony)" <urezki@xxxxxxxxx> Subject: mm: vmalloc: use trace_alloc_vmap_area event Date: Tue, 18 Oct 2022 20:10:50 +0200 This is for debug purpose and is called when an allocation attempt occurs. This event gives some information about: - start address of allocated area; - size that is requested; - alignment that is required; - vstart/vend restriction; - if an allocation fails.
