[PATCH v6 18/39] kasan, vmalloc: drop outdated VM_KASAN comment

[andrey . konovalov]

From: Andrey Konovalov <andreyknvl@xxxxxxxxxx>

The comment about VM_KASAN in include/linux/vmalloc.c is outdated.
VM_KASAN is currently only used to mark vm_areas allocated for
kernel modules when CONFIG_KASAN_VMALLOC is disabled.

Drop the comment.

- * If IS_ENABLED(CONFIG_KASAN_VMALLOC), VM_KASAN is set on a vm_struct after

- * Otherwise, VM_KASAN is set for kasan_module_alloc() allocations and used to
- * determine which allocations need the module shadow freed.
