Thanks Mates! I've seen those manuals but the bug I'm chasing doesn't

Just now that I got your attention :) one final clarification
question:
* the attribute cache (==metadata cache) is part of the nfs client
code
* the date (=file content) cache would be the normal linux caching
A file's mtime/ctime/atime is stored in the generic in-core inode.
The inode cache is "normal linux caching". File content is cached in
the kernel's regular page cache, also considered "normal linux
caching". The difference for NFS files is how this information is
updated and flushed back to persistent storage.
