find a small bug here

[No-47]

look at this picture above plz...we know that the type of "rest ", "data.blockSize" and "requiredSize" is std::size_t.
However, std::size_t is unsigned __int64. So they are unsigned. if you do "rest = affectedNode->data.blockSize - requiredSize", it will always get a value greater than zero. when "data.blockSize < requiredSize", it will be a great trouble ("rest" will be a Huge unsigned number).....
a better way is:

Hello

If the Find method returned a result (affectedNode), it means that affectedNode->data.blockSize is always greater or equals to requiredSize. Otherwise, there is not enough memory (and you may want to return nullptr)

However, in this piece of code, the if(rest > 0) may be replaced by if(rest > sizeof(Node)) since we need at least the room for a Node.

Have a good day,

can I do this as my first open source issue?
