Andrew Waterman	ca69d69a30	Handle unimplemented syscalls gracefully We previously kernel-panicked because that made it more obvious when a syscall implementation was missing. These days, it's more common that the C library will do something sensible in response to returning -ENOSYS. Favor that approach to avoid frustrating users.	4 years ago
