For a very long time, the NFS client has done readahead for directory blocks. Unlike data blocks, the readahead cannot begin until the Readdir RPC reply has been received, since the directory offset cookie in that Readdir RPC reply is needed. As such, the readahead is serialized and does not seem to provide any real benefit. Recent testing/benchmarking shows that removing this readahead code for Readdir does not have a negative impact on performance. Therefore, this patch deletes the readahead code for Readdir, which simplifies the code and may make future changes simpler. MFC after: 1 month |
