Subject: [PATCH v2 00/53] make MM selftests more CI friendly
Date: Sat, 18 Apr 2026 13:54:45 +0300 [thread overview]
Message-ID: <20260418105539.1261536-1-rppt@kernel.org> (raw)
From: "Mike Rapoport (Microsoft)" <rppt@kernel.org>
Hi,
There's a lot of dancing around HugeTLB settings in run_vmtests.sh.
Some test need just a few default huge pages, some require at least 256 MB, and
some just skip lots of tests if huge pages of all supported sizes are not
available.
The goal of this set is to make tests deal with HugeTLB setup and teardown.
There are already convenient helpers that allow easy reading and writing of
/proc and /sysfs, so adding a few APIs that will detect and update HugeTLB
settings shouldn't be a big deal. But these nice helpers use kselftest
framework, and many of HugeTLB (and even THP) test don't, so as a result this
patchset also includes a lot of churn for conversion of those tests to
kselftest framework (patches 7-19).
The series break out:
patches 1-4: small fixes
patches 7-19: mechanical conversion to kselftest framework
patches 20-26: extension of thp_settings to hugepage_settings to also include
HugeTLB helpers
patches 27-28: add helpers for setting up SHM limits in hugetlb-shm and
thuge-gen tests
patches 29-51: integrate the new APIs in all the tests that use HugeTLB
patches 52-53: drop HugeTLB setup from run_vmtests.sh
I belive at this point this can go to mm-new and wait there for more review
feedback.
Based on mm-stable-2026-04-18-02-14
v2 changes:
* fix hugetlb mmap tests to actually test file mappings
* increase maximal tests number in khugepaged
* add tags, thanks everyone!
