[module] MODULE_IMPORT_NS now requires a string literal in 6.13

Reference torvalds/linux@cdd30ebb1

Using a string literal still compiles on 6.11

Some news here? I am waiting for this PR

@netboy3 for what it's worth, I updated my PR, thanks for the helpful review on zeule's PR.

@ticpu i would suggest that you use if statements for the kernel module fix for 6.13 as this current patch breaks when building against kernel 6.12.X and older kernels for fedora atomic

I wonder if it's something specific to Fedora or Arch as this is supposed to be compatible for a long time. Like I said in my first post, it did compile or Arch's 6.11.
Thanks for the tip I'll check it out tonight.

you are welcome, it is probably a good idea to keep the old behavior on anything that is not 6.13+

Since I was mislead with my v6.11 build on ArchLinux, I decided to test it out with multiple kernels.

Without the patch, anything below 6.13-rc1 fails.

With #if'ed patch, I could build the module on vanilla 6.10, 6.14-rc1, Fedora's 6.12 and ArchLinux's 6.13.

I added both zeule and you as co-author since you both suggested to add the #if in the first place.
