From c8708a9275928cc8e77bd443cd12565dda0a3ded Mon Sep 17 00:00:00 2001 From: KaiGai Kohei Date: Sat, 13 May 2006 15:21:38 +0900 Subject: [PATCH] [JFFS2][XATTR] Handling the duplicate JFFS2_NODETYPE_XATTR node cases. When jffs2_sum_process_sum_data() found a JFFS2_NODETYPE_XATTR which has duplicate xid and older version, an error was returned without appropriate process. In the result, mounting filesystem is failed. This patch fix this problem. If jffs2_setup_xattr_datum() returned -EEXIST, the caller marks this node as DIRTY_SPACE().
