From 51104c19d8570eb23208e08eac0e9ae09ced1c15 Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Wed, 12 Jun 2024 12:59:18 -0700 Subject: kunit: test: Add vm_mmap() allocation resource manager For tests that need to allocate using vm_mmap() (e.g. usercopy and execve), provide the interface to have the allocation tracked by KUnit itself. This requires bringing up a placeholder userspace mm. This combines my earlier attempt at this with Mark Rutland's version[1]. Normally alloc_mm() and arch_pick_mmap_layout() aren't exported for modules, so export these only for KUnit testing.
