+.BI inode_badness_threshold= threshold_value
+A badness counter is associated with every inode, which determines the degree
+of inode corruption. Each error found in the inode will increase the badness
+by 1 or 2, and inodes with a badness at or above
+.I threshold_value
+will be prompted for deletion. The default
+.I threshold_value
+is 12, and must either be 0 (disabled), or between 3 and 200, as some valid
+inode states may set a badness of 1 or 2 that should not clear the inode.
