      [XFS] Radix tree based inode caching · da353b0d
      David Chinner authored
      One of the perpetual scaling problems XFS has is indexing it's incore
      inodes. We currently uses hashes and the default hash sizes chosen can
      only ever be a tradeoff between memory consumption and the maximum
      realistic size of the cache.
      
      As a result, anyone who has millions of inodes cached on a filesystem
      needs to tunes the size of the cache via the ihashsize mount option to
      allow decent scalability with inode cache operations.
      
      A further problem is the separate inode cluster hash, whose size is based
      on the ihashsize but is smaller, and so under certain conditions (sparse
      cluster cache population) this can become a limitation long before the
      inode hash is causing issues.
      
      The following patchset removes the inode hash and cluster hash and
      replaces them with radix trees to avoid the scalability limitations of the
      hashes. It also reduces the size of the inodes by 3 pointers....

      Initial git repository build. I'm not bothering with the full history,
      even though we have it. We can create a separate "historical" git
      archive of that later if we want to, and in the meantime it's about
      3.2GB when imported into git - space that would just make the early
      git days unnecessarily complicated, when we don't have a lot of good
      infrastructure for it.
      
      Let it rip!
