- * Simple key scheme
- * ~~~~~~~~~~~~~~~~~
- *
- * Keys are 64-bits long. First 32-bits are inode number (parent inode number
- * in case of direntry key). Next 3 bits are node type. The last 29 bits are
- * 4KiB offset in case of inode node, and direntry hash in case of a direntry
- * node. We use "r5" hash borrowed from reiserfs.
