That seems to fix the problem here, thanks!

The last potential issue I'm seeing (completely unrelated to your patch) 
is this:

[  340.610000] VFS: Lookup of '1' in vfat loop0 would have caused loop
[  354.360000] d_splice_alias: 1104 callbacks suppressed
[  354.360000] VFS: Lookup of '1' in vfat loop0 would have caused loop

Is that worth investigating closer?

Thanks,


Vegard
