From 57e3cded99e9c840bc5310878d0a7f4e7768a296 Mon Sep 17 00:00:00 2001 From: David Gow Date: Thu, 25 May 2023 12:21:30 +0800 Subject: kunit: kmalloc_array: Use kunit_add_action() The kunit_add_action() function is much simpler and cleaner to use that the full KUnit resource API for simple things like the kunit_kmalloc_array() functionality. Replacing it allows us to get rid of a number of helper functions, and leaves us with no uses of kunit_alloc_resource(), which has some usability problems and is going to have its behaviour modified in an upcoming patch. Note that we need to use kunit_defer_trigger_all() to implement kunit_kfree().
