WebThe file buddy-malloc.c implements a buddy memory allocator, which is an allocator that allocates memory within a fixed linear address range. It spans the address range with a binary tree that tracks free space. Both "malloc" and "free" are O (log N) time where N is the maximum possible number of allocations.
