-This ext4 feature allows more than 65000 subdirectories per directory.

+Normally ext4 allows an inode to have no more than 65,000 hard links.

+This applies to files as well as directories, which means that there can

+be no more than 64,998 subdirectories in a directory (because each of

+the '..' entries counts as a hard link).  This feature lifts this limit

+by causing ext4 to use a links count of 1 to indicate that the number of

+hard links to a directory is not known.
