Struct SyscallAllocFree 

pub struct SyscallAllocFree { /* private fields */ }

Dynamic memory allocation syscall called when the BPF program calls gema_alloc_free_(). The allocator is expected to allocate/free from/to a given chunk of memory and enforce size restrictions. The memory chunk is given to the allocator during allocator creation and information about that memory (start address and size) is passed to the VM to use for enforcement.
