The timeval_to_ns() function doesn't appear to be used anywhere, as far
as I (or git grep) can tell, and clang throws up a warning about it:
../arch/um/os-Linux/time.c:21:25: warning: unused function 'timeval_to_ns' [-Wunused-function]
static inline long long timeval_to_ns(const struct timeval *tv)
^
1 warning generated.

Warning can be reproduced under clang 13.0.1-+rc1 after applying:

Correct. Leftovers from the days when the timers subsystem was based on itimer_*() instead of POSIX timers.
