selftests: complete kselftest include centralization

2025-11-27T22:24:31Z

This follow-up patch completes centralization of kselftest.h and ksefltest_harness.h includes in remaining seltests files, replacing all relative paths with a non-relative paths using shared -I include path in lib.mk Tested with gcc-13.3 and clang-18.1, and cross-compiled successfully on riscv, arm64, x86_64 and powerpc arch.

selftests: filesystems: return Kselftest Skip code for skipped tests

2018-05-30T21:21:52Z

When devpts_pts test is skipped because of unmet dependencies and/or unsupported configuration, it exits with error which is treated as a fail by the Kselftest framework. This leads to false negative result even when the test could not be run. In another case, it returns pass for a skipped test reporting a false postive. Change it to return kselftest skip code when a test gets skipped to clearly report that the test could not be run. Change it to use ksft_exit_skip() when test is skipped.

selftests/filesystems: devpts_pts included wrong header

2018-05-30T21:21:51Z

We were picking up the wrong header should use asm/ioctls.h form the kernel and not the header from the system (sys/ioctl.h). In the current code we added the correct include and we added the kernel headers path to the CFLAGS.

selftests: add devpts selftests

2018-03-14T12:31:23Z

This adds tests to check: - bind-mounts from /dev/pts/ptmx to /dev/ptmx work - non-standard mounts of devpts work - bind-mounts of /dev/pts/ptmx to locations that do not resolve to a valid slave pty path under the originating devpts mount fail Signed-off-by: Christian Brauner Acked-by: "Eric W.
