selftests: add hugetlbfstest

2013-07-03T23:08:07Z

As the confusing naming indicates, this test has some overlap with pre-existing tests. Would be nice to merge them eventually. But since it is only test code, cleanliness is much less important than mere existence. Signed-off-by: Joern Engel Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

self-test: fix make clean

thuge-gen was forgotten. Fix it by removing the duplication, so we don't get too many repeats. Signed-off-by: Joern Engel Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

selftests: exit 1 on failure

2013-07-03T23:08:07Z

In case this ever gets scripted, it should return 0 on success and 1 on failure. Parsing the output should be left to meatbags. Signed-off-by: Joern Engel Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

vm selftests: print failure status instead of cause make error

selftests: add a test program for variable huge page sizes in mmap/shmget

2012-12-12T01:22:25Z

Also remove -Wextra because gcc-4.6 emits lots of irritating signed/unsigned comparison warnings. Signed-off-by: Andi Kleen Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

mm: move hugepage test examples to tools/testing/selftests/vm

2012-03-29T00:14:37Z

hugepage-mmap.c, hugepage-shm.c and map_hugetlb.c in Documentation/vm are simple pass/fail tests, It's better to promote them to tools/testing/selftests. Thanks suggestion of Andrew Morton about this. They all need firstly setting up proper nr_hugepages and hugepage-mmap need to mount hugetlbfs. So I add a shell script run_vmtests to do such work which will call the three test programs and check the return value of them. Changes to original code including below: a. add run_vmtests script b. return error when read_bytes mismatch with writed bytes. c. coding style fixes: do not use assignment in if condition [akpm@linux-foundation.org: build the targets before trying to execute them] [akpm@linux-foundation.org: Documentation/vm/ no longer has a Makefile. Fixes "make clean"] Signed-off-by: Dave Young Cc: Wu Fengguang Cc: Christoph Lameter Cc: Pekka Enberg Cc: Frederic Weisbecker Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
