6.1-stable review patch. If anyone has any objections, please let me know. ------------------ From: Joseph Qi <joseph.qi@xxxxxxxxxxxxxxxxx> [ Upstream commit d32840ad4a111c6abd651fbf6b5996e6123913da ] Now in ocfs2_local_free_info(), it returns 0 even if it actually fails. Though it doesn't cause any real problem since the only caller dquot_disable() ignores the return value, we'd better return correct as it is.
