I'm not sure but I would imagine that the inode isn't filled with zeroes. The directory entry in a/b for 'c' is removed and the inode is deallocated (in-core copy and disk copy) along with any blocks (which I assume in this case are none). The list of free inodes and blocks is then updated. So my guess is that the inode isn't cleared to zero, the reference to it is simply deleted so that it can be re-used by another file. -Sid.
