[PATCH] kselftests: dmabuf-heaps: Fix confused return value on expected error testing

by John Stultz

When I added the expected error testing, I forgot I need to set the return to zero when we successfully see an error. Without this change we only end up testing a single heap before the test quits.

[PATCH v3 6/6] security: apparmor: default KUNIT_* fragments to KUNIT_ALL_TESTS

[PATCH] selftests/vm/keys: fix a broken reference at protection_keys.c

by Mauro Carvalho Chehab

Changeset 1eecbcdca2bd ("docs: move protection-keys.rst to the core-api book") from Jun 7, 2019 converted protection-keys.txt file to ReST. A recent change at protection_keys.c partially reverted such changeset, causing it to point to a non-existing file: - * Tests x86 Memory Protection Keys (see Documentation/core-api/protection-keys.rst) + * Tests Memory Protection Keys (see Documentation/vm/protection-keys.txt) It sounds to me that the changeset that introduced such change 4645e3563673 ("selftests/vm/pkeys: rename all references to pkru to a generic name") could also have other side effects, as it sounds that it was not generated against uptream code, but, instead, against a version older than Jun 7, 2019.
