[PATCH 14/25] ocfs2: Move OLQF_CLEAN flag out of generic quota flags

Jan Kara
2014-12-18T15:38:02Z

OLQF_CLEAN flag is used by OCFS2 on disk to recognize whether quota
recovery is needed or not. We also somewhat abuse mem_dqinfo->dqi_flags
to pass this flag around. Use private flags for this to avoid clashes
with other quota flags / not pollute generic quota flag namespace.
