  Probably yes, I already noticed this and mailed Andrew a patch with this
file included.

  I didn't know this existed :) I'll use it in future. Thanks. The question
is how to fix this. Probably the best would be if didn't have to export new
header file, wouldn't it? We can split the headers into quota.h containing
structures and all other userspace stuff and quota_func.h carrying other
kernel-internal stuff like inline functions etc. Oh well...
