    ocfs2: export ocfs2_kset for online file check · 9dde5e4f
    Gang He authored
    When there are errors in the ocfs2 filesystem, they are usually
    accompanied by the inode number which caused the error.  This inode
    number would be the input to fixing the file.  One of these options
    could be considered:
    
    A file in the sys filesytem which would accept inode numbers.  This
    could be used to communication back what has to be fixed or is fixed.
    You could write:
    
      $# echo "<inode>" > /sys/fs/ocfs2/devname/filecheck/check
    
    or
    
      $# echo "<inode>" > /sys/fs/ocfs2/devname/filecheck/fix
    
    Compare with second version, I re-design filecheck sysfs interfaces,
    there are three sysfs files (check, fix and set) under filecheck
    directory (see above), sysfs will accept only one argument <inode>.
    Second, I adjust some code in ocfs2_filecheck_repair_inode_block()
    function according to upstream feedback, we cannot just add VALID_FL
    flag back as a inode block fix, then we will not fix this field
    corruption currently until having a complete solution.  Compare with
    first version, I use strncasecmp instead of double strncmp functions.
    Second, update the source file contribution vendor.
    
    This patch (of 4):
    
    Export ocfs2_kset object from ocfs2_stackglue kernel module, then online
    file check code will create the related sysfiles under ocfs2_kset
    object.  We're exporting this because it's built in ocfs2_stackglue.ko.
