Hi OGAWA. There are 2 cases: 1. The cluster can be used as a data cluster of a file - In which case we can write normally into it. 2. The cluster can be allocated to a new directory. In this case, the busy i_pos locations can not be used to create new entries until the correspnding inodes are evicted.
