Re: [PATCH] selftests/mm: Check for YAMA ptrace_scope configuraiton before modifying it

When running the memfd_secret test run_vmtests.sh unconditionally tries to confgiure the YAMA LSM's ptrace_scope configuration, leading to an error if YAMA is not in the running kernel:

# ./run_vmtests.sh: line 432: /proc/sys/kernel/yama/ptrace_scope: No such file or directory # # ---------------------- # # running ./memfd_secret # # ----------------------

Check that this file is present before trying to write to it.

The indentation here is a bit odd, and it doesn't seem great that we configure but don't restore ptrace_scope.
