I can produce the error with two fresh installed VMs.

I've noticed that the users who have tested your kernel got something in
common: the remote system mounted as cifs isn't in an Ubuntu server and
it's kernel seems to be older than Ubuntu's client one... Maybe it's
something that can help you to reproduce the problem yourself.

Many thanks for the successful investigation!
Running the ppa test kernel I can't reproduce the problem anymore. :-)
I use two cifs servers running Debian 11, with a couple of shares. With both
standard kernels (6.5.0-27, 6.5.0-28) copying inside a share fails immediately
on any server.
My
In my reproduction environment i am testing against synology smb server
too.

Yep, fantastic. I can reproduce this problem anytime so I can test
Hi everyone,
As promised, I uploaded test kernels to the below ppa:
https://launchpad.net/~mruffell/+archive/ubuntu/lp2060919-test
They are based on 6.5.0-27-generic to keep it simple.
It just has "cifs: fix flushing folio regression for 6.1 backport". Thats it.
Pretty small patch:

Hello,
I can't actually reproduce the issue, I seem to be missing something.

Title:
Remote filesystems mounted as CIFS not working
I can mount cifs shares with kernel 6.5.0-27, but when copying files from the
share to the same share the process is killed everytime. Same effect using bash
"cp" or KDE kio copy via Krusader.
Running with kernel 6.5.0-26 anything works perfect.

That kernel is from the "linux-hwe-6.5" package. I'll try to link this
bug to that package to avoid duplication.
