Yes, I am aware of the page cache limit. My question is more theoretical
of nature, anyway.

What I wanted to know is just that: there are limits with Linux due to the
page cache, the block device etc etc. But what limit does the XFS code
itself have, dependent on the block size 4k,16k,64k.

Or the other way round: on an IRIX Octane, what is the maximum file system
limit for 4k blocksize?

Best regards and many thanks
