    Description

      The patch implements an extended attribute cache for
      a Lustre client. It is organized as a write-through
      cache: reads are performed from cache, updates are sent
      synchronously to the MDS. An additional inode bit
      is added to protect the cache.

      The patch itself will be uploaded shortly.
