Hi, The 1st 6 patch removes all kinds of debugfs dir entries of block layer, instead always retrieves them debugfs, so avoid to maintain block internal debugfs state. The 7 patch removes debugfs_mutex for adding/removing debugfs entry because we needn't the protection any more, then one lockdep warning can be fixed.
