"adversely"? The patch is an improvement, not something that makes things
worse...

Huh? Atime updates in the old NTFS driver do not happen at all unless I
have missed something.
Otherwise, the time resolution itself is down to 100ns intervals which in
Linux obviously isn't possible, so the Linux atime resolution will be used
instead.
The new NTFS TNG driver will be doing the atime updates properly once write
support is implemented.
Best regards,
Anton
