------------------------------------------------------
Subject: quota: split out quota_struct.h out of quota.h
From: Jan Kara <jack@xxxxxxx>

Split some structure definitions from quota.h to quota_struct.h so that
they can be separately included in fs.h.  This makes it possible to
declare some useful inline functions in quota.h because it can now include
fs.h.
