ktime: Use macro NSEC_PER_USEC where appropriate (a44b8bd6) · Commits · 戴 / test

We've got the macro NSEC_PER_USEC defined in header file include/linux/time.h. To make the code decent, this patch replaces the immediate number 1000 to convert bewteen a time value in microseconds and one in nanoseconds with the macro NSEC_PER_USEC. Signed-off-by:
