Merge tag 'linux-kselftest-5.7-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest
Pull kselftest updates from Shuah Khan: - ftrace test fixes to check for required filter files and kprobe args. - Kselftest build/cross-build dependency check script to make it easier for test ring admins/users to configure build systems correctly for build/cross-build kselftests. Currently checks library dependencies. - Checks if Kselftests can be built/cross-built on a system running compile test on a trivial C file with LDLIBS specified for each individual test in their Makefiles. - Prints suggested target list for a system filtering out tests failed the build dependency check from the TARGETS in Selftests the main Makefile when optional -p is specified. - Prints pass/fail dependency check for each tests/sub-test. - Prints pass/fail targets and libraries. - Default: runs dependency checks on all tests. - Optional test name can be specified to check dependencies for it. * tag 'linux-kselftest-5.7-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest: selftests/ftrace: Check the first record for kprobe_args_type.tc selftests: add build/cross-build dependency check script selftests/ftrace: Check required filter files before running test
