Close to open consistency

Hi there,

I have some queries regarding NFS' implementation of close to open
consistency. I hope this is the correct forum.

I believe the following to be obviously correct from the various
references on the subject: if I open, write a new file on one client,
close it and then immediately attempt to open and read the file on
another client, I will always see the file as created by the first
client (assuming no other intervening actions by other clients).

However what if, instead of the second client calling open on the
file, it immediately calls just exec (assume the file is an
executable)? Presumably at some point in the exec call it is at least
implicitly invoking some of the functionality of open but is the above
consistency still guaranteed here? Is it only explicit calls to open
which maintain the consistency?

Thanks!
