Output that follows:

1. First free block 0xb7cf0ff8, last free 0xb7cf0fe8, total free 58036
2. First locked block 0xb7cf0fd8, last locked 0xb7cf0fc8
3. First used block = 0xb7cf0fb8, last used block = 0xb7cf0fb8, found_used_block = 0
4. Free and used blocks are not adjacent.
5. no unlocked blocks

Explanation:

1. 0xb7cf1008 locked block skipped
2. 0xb7cf0ff8 - 0xb7cf0fe8 free
3. 0xb7cf0fd8 - 0xb7cf0fc8 locked
4. 0xb7cf0fb8 used too large
5. stop.

Needs to look further for smaller used blocks to move (skipping over potential free blocks!), then continuing again from the first free block and re-link the blocks moved. Relinking blocks is always messy.
