From: Claude <noreply@anthropic.com>
This series moves the hugetlb test library and the numa cpuset helper
into the global libs/ location, following the tse_ naming scheme adopted
for the extended (non-core) libraries, and fixes an out-of-bounds write
found during review.
The remaining helpers from #1276 are left as follow-ups: numa_helper.c
still uses the legacy test API and should be rewritten before being
moved, and the placement of the single ksm_helper.c function is still
open.
Part of #1276
Changes in v3:
- Split the two independent migrations into separate patches, as
requested in review (hugetlb library vs write_node_cpusets()).
- New patch 3/3: fix the out-of-bounds write in gather_node_cpus()
when a node has no online CPUs, reported in review (pre-existing,
predates the move).
- Rebased onto current master; converted the newly added tests
(hugemmap35, hugemmap36, hugemmap37, hugemmap38, hugemmap41) to the
tse_hugetlb.h header.
Changes in v2:
- Rebased onto the merged tse_ naming scheme (v1 still used tst_).
- Fix the ksm02 link failure reported on v1: ksm02, ksm04, oom04 and
oom05 now link -lltpnuma.
- Use the standard LTPLIBS mechanism for the hugetlb tests instead of
a hand-rolled Makefile.inc.
- Size the per-CPU sysfs path buffer to avoid -Wformat-truncation.
