From aad1b15310b9bcd59fa81ab8f2b1513b59553ea8 Mon Sep 17 00:00:00 2001 From: Tiger Yang Date: Thu, 19 Nov 2009 10:17:46 +0800 Subject: [PATCH] ocfs2: return -EAGAIN instead of EAGAIN in dlm We used to return positive EAGAIN to indicate a retry action is needed in dlm_begin_reco_handler(). Now we return negative -EAGAIN to erase the confusion caused by this error code.
