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

userfaultfd: selftest: vm: allow to build in vm/ directory linux/tools/testing/selftests/vm $ make gcc -Wall -I ../../../../usr/include compaction_test.c -lrt -o /compaction_test /usr/lib/gcc/x86_64-pc-linux-gnu/4.9.4/../../../../x86_64-pc-linux-gnu/bin/ld: cannot open output file /compaction_test: Permission denied collect2: error: ld returned 1 exit status make: *** [../lib.mk:54: /compaction_test] Error 1 Since commit a8ba798bc8ec ("selftests: enable O and KBUILD_OUTPUT") selftests/vm build fails if run from the "selftests/vm" directory, but it works in the selftests/ directory. It's quicker to be able to do a local vm-only build after a tree wipe and this patch allows for it again.

userfaultfd: selftests: vm: pick up sanitized kernel headers Add the usr/include subdirectory of the top-level tree to the include path, and make sure to include headers without relative paths to make sure the sanitized headers get picked up. Otherwise the compiler will not be able to find the linux/compiler.h header included by the non- sanitized include/uapi/linux/userfaultfd.h. While at it, make sure to only hardcode the syscall numbers on x86 and PowerPC if they haven't been properly picked up from the headers.

selftests: add default rules for c source file There are difference rules for compiling c source file in different testcases. In order to enable KBUILD_OUTPUT support in later patch, this patch introduce the default rules in "tools/testing/selftest/lib.mk" and remove the existing rules in each testcase.

selftests: remove duplicated all and clean target Currently, kselftest use TEST_PROGS, TEST_PROGS_EXTENDED, TEST_FILES to indicate the test program, extended test program and test files. It is easy to understand the purpose of these files. But mix of compiled and uncompiled files lead to duplicated "all" and "clean" targets. In order to remove the duplicated targets, introduce TEST_GEN_PROGS, TEST_GEN_PROGS_EXTENDED, TEST_GEN_FILES to indicate the compiled objects. Also, the later patch will make use of TEST_GEN_XXX to redirect these files to output directory indicated by KBUILD_OUTPUT or O. And add this changes to "Contributing new tests(details)" of Documentation/kselftest.txt.

selftests: Introduce minimal shared logic for running tests This adds a Make include file which most selftests can then include to get the run_tests logic. On its own this has the advantage of some reduction in repetition, and also means the pass/fail message is defined in fewer places. However the key advantage is it will allow us to implement install very simply in a subsequent patch. The default implementation just executes each program in $(TEST_PROGS). We use a variable to hold the default implementation of $(RUN_TESTS) because that gives us a clean way to override it if necessary, ie. using override. The mount, memory-hotplug and mqueue tests use that to provide a different implementation. Tests are not run via /bin/bash, so if they are scripts they must be executable, we add a+x to several.

Let's combine all the cases into a single executable which will have a command line option for selection of the test type.
