[PATCH] tests: switch nap() to use file creation to gauge delay

2024-06-28 Thread Jeff Layton
The current test in nap.h tries to gauge the minimum delay that results in a timestamp change when successively writing to a file. There are some proposed changes [1] to track finer-grained timestamps in the Linux kernel that will break the assumptions that nap() uses to gauge the delay. In partic
