Definitely we have to hide projectid under kernel config option, bu,t what option should it be? We have two choices 1) CONFIG_QUOTA: because most of users who use quota probably will also use project id support 2) introduce new config option: This may be reasonable if projectid may be usefull witout quota and inode size is critical.
