Ganesha invalidates directory dirent in mdcache_getattrs depends on

But the time accuracy is 1s.
If there are many creating after one readdir in 1s,
how to make sure the dirents in mdcache is synchronous as lower filesystem?
I wanna know, can we update it to depends on mtime.tv_usec?
Are there some problems or some other considers?
In mdcache_refresh_attrs(), it uses gsh_time_cmp() to check of the mtime
has changed. That compares tv_sec and tv_nsec, so it should already be
comparing to the limit of the filesystem's resolution.
