Why does the `sa` command (from the acct package) always show "0" for avio?

For example, I get:

These processes are definitely reading and writing to disk so I expect a non-zero value for disk i/o related statistics.

Is there a kernel flag or compile flag or command option to get a value for "avio" (also "tio" is not even listed)?

Thank you!

I am not a c-programmer, but the `0` is probably originating from the source, see line #955 here: https://github.com/Whissi/gnu-acct/blob/master/sa.c

I just updated my question to clarify that I expect these processes to be consuming disk i/o so I expect a non-zero number. Is there something on line #955 that suggests a configuration change I need to make to get these values to be populated? Or are you suggesting: if it says 0 it means there is no disk i/o for the process?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
