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.
