reiserfs builds files of items. Item is stored in an ondisk tree. Each
file has at least one item - stat data item. Each item has key. Key has
4 components.
[52570 52653 0x0 SD] is key of stat data. Key of stat data was taken
from directory entry.
First key component is unique identifier of directory in which file was
created.
Second key component is unique identifier of file itself. This is what
is reported in st_ino field of struct stat
Third key component is offset within a file. It is 0 for items if stat
data type.
Fourth key component is item type.
