Subject: [PATCH 0/3] ext4: fix a inode checksum error
Date: Tue, 10 Aug 2021 22:27:19 +0800	[thread overview]
Message-ID: <20210810142722.923175-1-yi.zhang@huawei.com> (raw)

We find a checksum error and a inode corruption problem while doing
stress test, this 3 patches address to fix them.

 - Checksum error

    EXT4-fs error (device sda): ext4_lookup:1784: inode #131074: comm cat: iget: checksum invalid

 - Inode corruption

    e2fsck 1.46.0 (29-Jan-2020)
    Pass 1: Checking inodes, blocks, and sizes
    Pass 2: Checking directory structure
    Entry 'foo' in / (2) has deleted/unused inode 17.  Clear<y>? yes
    Pass 3: Checking directory connectivity
    Pass 4: Checking reference counts
    Pass 5: Checking group summary information
    Inode bitmap differences:  -17
    Fix<y>? yes
    Free inodes count wrong for group #0 (32750, counted=32751).
    Fix<y>? yes
    Free inodes count wrong (32750, counted=32751).
    Fix<y>? yes

The first patch is relate to the error simulation, and the second patch
is just a cleanup patch, which are prepare to do the fix. The last patch
fix these two issue.

Thanks,
Yi.
