Title:
  CIFS stopped working/is unstable with kernel update to 5.15.0-102.112

Status in linux package in Ubuntu:
  Invalid
Status in linux source package in Jammy:
  Fix Committed

Bug description:
  Hi,

  updated some Ubuntu 22.04 systems to lastest available state this
  morning, which caused CIFS mounts (from various fileservers) to stop
  working. Kernel was updated to version 5.15.0-102-generic.

  I can mount the shares without problems (mount -t cifs), but then, df for 
example tells me: df: /mnt: Resource temporarily unavailable.
  I'm able to list and browse all the files, but accessing them (even readonly) 
is very unstable. Sometimes it works and sometimes it just gives me i/o errors. 

  Switching back to  5.15.0-101-generic or 5.15.0-100-generic solves the
  problem and everything works again as expected.

  Seems like some bug has been implemented in 5.15.0-102-generic...

  To reproduce the problem, I started a while loop on one server to
  write to some file on a specific mounted CIFS share and read it from
  another one

  root@<hostname1>:~# while true; do echo "$(date) hallo" >> /mnt/hallo.txt; 
sleep 1 ; done
  -bash: /mnt/hallo.txt: Input/output error
  -bash: /mnt/hallo.txt: Input/output error
  ^C

  root@<hostname2>:~$ tail -f /mnt/hallo.txt
  Tue Apr  9 04:10:52 PM CEST 2024 hallo
  Tue Apr  9 04:10:53 PM CEST 2024 hallo
  Tue Apr  9 04:10:54 PM CEST 2024 hallo
  Tue Apr  9 04:10:55 PM CEST 2024 hallo
  Tue Apr  9 04:10:56 PM CEST 2024 hallo
  Tue Apr  9 04:10:57 PM CEST 2024 hallo
  Tue Apr  9 04:10:58 PM CEST 2024 hallo
  Tue Apr  9 04:10:59 PM CEST 2024 hallo
  Tue Apr  9 04:11:00 PM CEST 2024 hallo
  Tue Apr  9 04:11:01 PM CEST 2024 hallo
  tail: cannot determine location of '/mnt/hallo.txt'. reverting to polling: 
Resource temporarily unavailable
  Tue Apr  9 04:11:04 PM CEST 2024 hallo
  Tue Apr  9 04:11:05 PM CEST 2024 hallo
  Tue Apr  9 04:11:06 PM CEST 2024 hallo
  Tue Apr  9 04:11:07 PM CEST 2024 hallo
  Tue Apr  9 04:11:08 PM CEST 2024 hallo
  Tue Apr  9 04:11:09 PM CEST 2024 hallo
  Tue Apr  9 04:11:10 PM CEST 2024 hallo

  While doing this, both servers tell me, the resource is unavailable

  root@<hostname1>:~# df -h /mnt
  df: /mnt: Resource temporarily unavailable

  root@<hostname2>:~$ df -h /mnt
  df: /mnt: Resource temporarily unavailable
