Subject: [PATCH v6 3/6] tools/lib/mm: move hugepage_settings out of selftests
Date: Thu, 30 Jul 2026 19:38:22 +0530 [thread overview]
Message-ID: <20260730140825.238130-4-sarthak.sharma@arm.com> (raw)
In-Reply-To: <20260730140825.238130-1-sarthak.sharma@arm.com>
Move hugepage_settings.[ch] from tools/testing/selftests/mm/ to
tools/lib/mm/ so the THP and HugeTLB helpers can be shared more easily
between selftests and other tools.
Keep the helpers exposed to mm selftests through vm_util.h where possible,
and use direct <mm/hugepage_settings.h> includes for files that do not
include vm_util.h. Adjust the selftests/mm build to compile the moved
implementation from its new location.
Remove the remaining kselftest dependency from hugepage_settings.c.
Replace ksft_perror() with a new print_file_error() helper and
ksft_print_msg() with printf(). Prefix both with a # to keep them
TAP compatible.
