But now the flag for\nringbuf area is VM_ALLOC, so KASAN will complain out-of-bound access\nafter vmap() returns. Because the ringbuf area is created by mapping\nallocated pages, so use VM_MAP instead.\n\nAfter the change, info in /proc/vmallocinfo also changes from\n  [start]-[end]   24576 ringbuf_map_alloc+0x171/0x290 vmalloc user\nto\n  [start]-[end]   24576 ringbuf_map_alloc+0x171/0x290 vmap user"
