Hi all, I'm reading EXT4 codes and has some questions about readdir implementation. Why traverse the directory in hash order? This brings lots of code to build and traverse a red-black tree. Why not just plainly traverse the directory's blocks? Since the red-black tree is built every time a NFS readdir request comes in, in case of hash collision, the nfs client may receive duplicate dir entries if the buffer is not large enough to return all entries with the same hash value in once.
