From 76068c4ff1cc03d9d24d17fd9e6a1475bc2f6730 Mon Sep 17 00:00:00 2001 From: Ryusuke Konishi Date: Mon, 6 Apr 2009 19:01:50 -0700 Subject: [PATCH] nilfs2: fix buggy behavior seen in enumerating checkpoints This will fix the weird behavior of lscp command in listing continuously created checkpoints; the output of lscp is rewinded regularly for the recent nilfs. As a result of debugging, a defect was found in nilfs_cpfile_do_get_cpinfo() function. Though the function can be repeatedly called to enumerate checkpoints and it can skip invalid checkpoint entries, the index value was not carried between successive calls. The bug has long been present, and came to surface after applying a bugfix nilfs2-fix-problems-of-memory-allocation-in-ioctl.patch, which increased frequency of calling the function. The similar bugfix was already applied for ``snapshots'' by nilfs2-fix-gc-failure-on-volumes-keeping-numerous-snapshots.patch. This fixes the problem by making the index argument bidirectional on the function.
