Why does 'stat -c%s\ %b small_dir_size' report a 0 block size?
 
Code:
~/tmp]$ mkdir test1
~/tmp]$ echo abcd >> test1/test.txt
~/tmp]$ stat -c"size in bytes: %s, size in blocks: %b, size of a block: %B" test1
size in bytes: 21, size in blocks: 0, size of a block: 512
~/tmp]$
xfs file system, 4kB minimum allocation unit on disk

I guess that the file is so small that it is entirely contained in the inode (reference), not occupying any data blocks.

I think that only du can report the allocated blocks properly.

stat, ls -l and du are fully coherent on this.

The same reference as given by berndbausch, but more relevant part: Shortform Directories.
