Hello,
There is unused (in some cases) pointer in dquot.c
fs/quota/dquot.c:135: warning: ‘quotatypes’ defined but not used

which is referenced only when 
#ifdef CONFIG_QUOTA_DEBUG or #ifdef CONFIG_PRINT_QUOTA_WARNING

My proposal is to wrap declaration in "if defined(CONFIG_QUOTA_DEBUG) || defined(CONFIG_PRINT_QUOTA_WARNING) ..."?
