    [PATCH] ext3: wrong error behavior · 7543fc7b
    Vasily Averin 提交于
    SWsoft Virtuozzo/OpenVZ Linux kernel team has discovered that ext3 error
    behavior was broken in linux kernels since 2.5.x versions by the following
    patch:
    
    2002/10/31 02:15:26-05:00 tytso@snap.thunk.org
    Default mount options from superblock for ext2/3 filesystems
    http://linux.bkbits.net:8080/linux-2.6/gnupatch@3dc0d88eKbV9ivV4ptRNM8fBuA3JBQ
    
    In case ext3 file system is mounted with errors=continue
    (EXT3_ERRORS_CONTINUE) errors should be ignored when possible.  However at
    present in case of any error kernel aborts journal and remounts filesystem
    to read-only.  Such behavior was hit number of times and noted to differ
    from that of 2.4.x kernels.
    
    This patch fixes this:
    - do nothing in case of EXT3_ERRORS_CONTINUE,
    - set EXT3_MOUNT_ABORT and call journal_abort() in all other cases
    - panic() should be called after ext3_commit_super() to save
     sb marked as EXT3_ERROR_FS
