The ext2fs_link helper function link_proc does not check the value of ls->done, which means that if the function finds multiple empty spaces that will fit the new directory entry, it will create a directory entry in each of the spaces. Instead of doing that, check the done value and don't do anything more if we've already added the directory entry. Signed-off-by: Darrick J.
