      nfsd: allow turning off nfsv3 readdir_plus · 18c01ab3
      Rajesh Ghanekar 提交于
      One of our customer's application only needs file names, not file
      attributes. With directories having 10K+ inodes (assuming buffer cache
      has directory blocks cached having file names, but inode cache is
      limited and hence need eviction of older cached inodes), older inodes
      are evicted periodically. So if they keep on doing readdir(2) from NSF
      client on multiple directories, some directory's files are periodically
      removed from inode cache and hence new readdir(2) on same directory
      requires disk access to bring back inodes again to inode cache.
      
      As READDIRPLUS request fetches attributes also, doing getattr on each
      file on server, it causes unnecessary disk accesses. If READDIRPLUS on
      NFS client is returned with -ENOTSUPP, NFS client uses READDIR request
      which just gets the names of the files in a directory, not attributes,
      hence avoiding disk accesses on server.
      
      There's already a corresponding client-side mount option, but an export
      option reduces the need for configuration across multiple clients.
      
      This flag affects NFSv3 only.  If it turns out it's needed for NFSv4 as
      well then we may have to figure out how to extend the behavior to NFSv4,
      but it's not currently obvious how to do that.
