From d882687c51b52424a56992578ce7636b3f3c8d41 Mon Sep 17 00:00:00 2001 From: Havasi Ferenc Date: Tue, 5 Sep 2006 16:08:58 +0200 Subject: [PATCH] [JFFS2][SUMMARY] Fix a summary collecting bug. In some special case (padding because of sync or umount) it can be possible that summary information is not fit to the end of the erase block. In these cases the collecting of summary is disabled for this erase block. The problem was that this was not respected by jffs2_sum_add_kvec(). This patch fix this bug.
