Hi all!
As soon as we have tunable actimeo, I think we should revalidate inode
all the time we want to read from it, like NFS does it.
What do you think about it? If it's ok, I am ready to provide a patch for this.

Did you mean while using strict cache along with actimeo? Conceptually
one should not be needing to use them together, right?

I don't mean strict cache mode and suggested to do it for
non-strictcache mounts. Sorry for didn't make it clear in the first
email.

I think it's a reasonable thing to do. I proposed something similar
about a year ago, but Steve NAK'ed it. It was part of this patchset,
some of which made it in:
