Valgrind complains that it does not know the fsmount syscall, pytest checks for warnings, find that and fails the test --14936-- WARNING: unhandled amd64-linux syscall: 430 --14936-- You may be able to write your own handler. --14936-- Read the file README_MISSING_SYSCALL_OR_IOCTL. --14936-- Nevertheless we consider this a bug. Please report --14936-- it at http://valgrind.org/support/bug_reports.html. fuse: fsopen(fuse) failed: Function not implemented =========================== short test summary info Obviously we want to filter our valgrind warnings.
