示例1: addBlocksForFileWrite

// patching up the referenced inode to match
func (w *InodeWriter) addBlocksForFileWrite(inode *maggiefs.Inode, off uint64, length uint32) error {

// if we have a last block and it's less than max length,
// extend last block to max block length first
// fmt.Printf("Adding/extending blocks for file write to inode %+v\n", inode)
