From 120b116208a0877227fc82e3f0df81e7a3ed4ab1 Mon Sep 17 00:00:00 2001 From: Liam Howlett Date: Fri, 28 Oct 2022 18:04:30 +0000 Subject: maple_tree: reorganize testing to restore module testing Along the development cycle, the testing code support for module/in-kernel compiles was removed. Restore this functionality by moving any internal API tests to the userspace side, as well as threading tests. Fix the lockdep issues and add a way to reduce memory usage so the tests can complete with KASAN + memleak detection. Make the tests work on 32 bit hosts where possible and detect 32 bit hosts in the radix test suite.
