TODO

   1 * We may need a libefi replacement.  It appears libefi is used
   2   to determine if the device passed to zpool is a 'whole device'
   3   or just a partition of a device.  In the short term I think we
   4   can simply treat everything as a partition and be alright.
   5
   6 * We also do not have support for getting Solaris style device
   7   ids which is done when a zpool is setup.  We may or may not
   8   be able to live without this, the jury is still out.

  12 * Port zvol (ZFS volume interface).
  13
  14 * Port zpl (ZFS posix interface).
  15
  16 * Port lustre fsfilt interface to use DMU.

  18 * Andreas issue #1:
  19   "the maximum allocation DMU "blocksize" was 128kB and it would be better
  20   to be able to get 1MB contiguous allocations for best performance"
  21
  22 * Andreas issue #2:
  23   "there would need to be some work done to allow multiple operations to
  24   be atomic.  This is needed by Lustre for object creation + LAST_ID
  25   updates, unlink + llog updates, etc.  Conceptually this isn't very
  26   much work for a phase tree, but I've never looked at the ZFS code."

  28 * Design and implement mechanism for viewing and modifying OST content
  29   from user space (by manipulating datasets/objects), possibly
  30   by implementing scaled down file system interface.
