Section section-6.2. says:
https://tools.ietf.org/html/rfc7530#section-6.2.1 The client can use the OPEN or ACCESS operations to check access without modifying or reading data or metadata.
It should say:
The client can use the OPEN or ACCESS operations to check access without modifying or reading data.
Whenever client does OPEN/ACCESS call, there is an inadvertent change in the Last Access time of the file. Hence we think that the Metadata is modified due to OPEN/ACCESS call. Hence the Suggestion is to change the text as above.
