This bug is awaiting verification that the linux-gcp/6.2.0-1019.21
kernel in -proposed solves the problem. Please test the kernel and
update this bug with the results. If the problem is solved, change the
tag 'verification-needed-lunar-linux-gcp' to 'verification-done-lunar-
linux-gcp'. If the problem still exists, change the tag 'verification-
needed-lunar-linux-gcp' to 'verification-failed-lunar-linux-gcp'.


If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.


See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

Title:
  Include cifs.ko in linux-modules package

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

Bug description:
  SRU Justification:

  [Impact]

  Commit: "smb: move client and server files to common directory fs/smb" 
introduced in 2023.09.04 moved the fs/cifs directory to fs/sb/client. The 
inclusion list for linux-modules was not updated, it still contains the old 
path. This means that the cifs.ko module cannot be loaded if only linux-modules 
package is installed, now being part of linux-modules-extra.
  For lunar:main this is not a problem because linux-modules-extra is always 
installed, but for derivatives like aws, azure etc, this module cannot be 
loaded without explicitly installing linux-modules-extra.

  [How to reproduce it]:
  1. Install the latest azure kernel 6.2.0-1016.16
  2. Load cifs module
  $ modprobe cifs
  modprobe: FATAL: Module cifs not found in directory 
/lib/modules/6.2.0-1016-azure
  If modules-extra is installed, this works.

  [Fix]

  Replace fs/cifs/* with fs/smb/client/* in 
debian.<derivative>/control.d/<derivative>.inclusiojn-list
  This is going to be done in s2023.10.02 cycle for derivatives.

  [Test Plan]

  1. Apply the fix to one of the derivative (azure), build a new kernel and 
install it
  2. Load cifs module
  $ modprobe cifs
  It should work without installing modules-extra.

  [Regression potential]

  Very low, it's a straightforward fix.

  [Other Info]
  Sending a patch for every derivative takes time and each derivative will be 
fixed once this proposal is acked.
  There is also the possibility to do it via cranky fix, but owners may omit it 
during security updates and it's hard to enforce it. Plus, it is a one-time 
change.
