[RFC 0/6] Migration deprecated parts

[Juan Quintela]

Hi this series describe the migration parts that have to be deprecated.

- It is an rfc because I doubt that I did the deprecation process right. Hello 
Markus O:-)

- skipped field: It is older than me, I have never know what it stands
  for.  As far as I know it has always been zero.

- inc/blk migrate command options.  They are only used by block
  migration (that I deprecate on the following patch).  And they are really bad.
  grep must_remove_block_options.

- block migration.  block jobs, whatever they are called this week are
  way more flexible.  Current code works, but we broke it here and
  there, and really nobody has stand up to maintain it.  It is quite
  contained and can be left there.  Is anyone really using it?

- old compression method.  It don't work.  See last try from Lukas to
  make a test that works reliabely.  I failed with the same task years
  ago.  It is really slow, and if compression is good for you, multifd
  + zlib is going to perform/compress way more.

  I don't know what to do with this code, really.

  * Remove it for this release?  It don't work, and haven't work
    reliabely in quite a few time.

  * Deprecate it and remove in another couple of releases, i.e. normal
    deprecation.

  * Ideas?

- -incoming <uri>

  if you need to set parameters (multifd cames to mind, and preempt has
  the same problem), you really needs to use defer.  So what should we do here?

  This part is not urget, because management apps have a working
  option that are already using "defer", and the code simplifacation
  if we remove it is not so big.  So we can leave it until 9.0 or
  whatever we think fit.

What do you think?

Later, Juan.
