Adds
buddy_alloc_size
function in accordance with #143.I wasn't sure where to put the function in the file, so I put it under the function
buddy_safe_free
, alongside the other allocation related functions. Is this an appropriate place for this function?Also, is the error handling correct? I saw an other function calls
buddy_tree_valid
to validate a position, is there anything I missed when it comes to the error handling?
