Mount options?  Time stamp granularity?

The file system I encountered this initially on is

/dev/sda7 on /usr/local type ext4 (rw,noatime,discard,data=ordered)

and my /tmp file system where I also saw this is

/dev/sda5 on / type ext4 (rw,noatime,discard)

I don't know whether Emacs uses /run/lock , if it does that would be

tmpfs on /run/lock type tmpfs (rw,nosuid,nodev,noexec,relatime,size=5120k)

The noatime option is because this is an SSD where I want to minimize
write wear.
