Add the ability to run one or more groups of vm tests (specified
by the environment variable TEST_ITEMS). Preserve existing default
behavior of running all tests when TEST_ITEMS is empty or "default".
Documentation of test groups is included in the patch as follows:
# ./run_vmtests.sh [ -h || --help ]
usage: ./tools/testing/selftests/vm/run_vmtests.sh [ -h ]
-h: display this message
The default behavior is to run all tests.
Alternatively, specific groups tests can be run by defining
the TEST_ITEMS shell variable with a space-separated string
of one or more of the following:
- mmap
tests for mmap(2)
- gup_test
tests for gup using gup_test interface
- userfaultfd
tests for userfaultfd(2)
- compaction
a test for the patch "Allow compaction of unevictable pages"
- mlock
tests for mlock(2)
- mremap
tests for mremap(2)
- hugevm
tests for very large virtual address space
- vmalloc
vmalloc smoke tests
- hmm
hmm smoke tests
- madv_populate
test memadvise(2) MADV_POPULATE_{READ,WRITE} options
- memfd_secret
test memfd_secret(2)
- process_mrelease
test process_mrelease(2)
- ksm
ksm tests that do not require >=2 NUMA nodes
- ksm_numa
ksm tests that require >=2 NUMA nodes
example: TEST_ITEMS="hmm mmap ksm" ./run_vmtests.sh
