I just noticed that I'm getting one-second resolution on all my
timestamps. This is for both ext4 and vfat partitions, and shows up in ls
--full-time and the stat command. What could account for this? My uname -a
output is "Linux CHROMA1 4.10.17-yocto-preempt-rt #1 SMP PREEMPT Wed Oct
11 12:33:54 PDT 2017 i686 i686 i386 GNU/Linux" if that's any help. Also,
my ext4 mount options are "rw,noatime,nodiratime,data=ordered".
I think file timestamp resolution on ext4 is one of the things that
depend on inode size (ext4 does not enforce reasonable values because
of compatibility with earlier versions I guess). So maybe check inode
size (should be 256 bytes I think?).
