Greetings: I'm using btrfs on Debian 10. When using "ls -l" to view a detailed listing in the current directory, I get output similar to the following: total 0 drwxrwx--- 1 jfrankli jfrankli 38 Feb 25 09:54 Desktop/ drwxrwx--- 1 jfrankli jfrankli 36 Jan 24 10:37 Documents/ drwxrwx--- 1 jfrankli jfrankli 612 Feb 24 15:48 Downloads/ drwxrwx--- 1 jfrankli jfrankli 0 Nov 6 04:44 Music/ drwxrwx--- 1 jfrankli jfrankli 20 Nov 6 04:44 Pictures/ drwxrwx--- 1 jfrankli jfrankli 0 Nov 6 04:44 Public/ drwxrwx--- 1 jfrankli jfrankli 0 Dec 27 20:20 Templates/ drwxrwx--- 1 jfrankli jfrankli 0 Dec 27 20:20 Videos/ drwxrwx--- 1 jfrankli jfrankli 522 Nov 26 09:53 bin/ drwxrwx--- 1 jfrankli jfrankli 28 Dec 27 15:23 snap/ Notice that these are all directories with a hard link count of "1". I have always seen directories possessing a hard link count of "2" or greater. This is because the directory itself is a hard link, and it also contains the "." entry (the second hard link). Any immediate child directory of a directory also adds +1 to the hard link count on other file systems. This is because each child directory contains the ".." hard link pointing to its parent directory. Why does this not happen with btrfs? Could it a bug with the GNU "ls" tool? -- Jason Franklin
