Subject: selftests/mm: kvm, mdwe fixes to avoid requiring "make headers"
Date: Thu, 13 Jun 2024 19:30:08 -0700
On Ubuntu 23.04, the kvm and mdwe selftests/mm build fails due to missing
a few items that are found in prctl.h. Here is an excerpt of the build
failures:
ksm_tests.c:252:13: error: use of undeclared identifier 'PR_SET_MEMORY_MERGE'
...
mdwe_test.c:26:18: error: use of undeclared identifier 'PR_SET_MDWE'
mdwe_test.c:38:18: error: use of undeclared identifier 'PR_GET_MDWE'
Fix these errors by adding the missing items to vm_util.h, and include
vm_util.h from mdwe_test.c.
