cluster/unify: don't call xl_init_tree on namespace node.

2010-01-15T07:23:42+00:00

- just before xl_init_tree call on namespace, unify node is set as parent of
    namespace node and since xl->ready of unify node is set only after return
    from init call, calling xl_init_tree on namespace node will result in
    execution of init of unify node for the second time. This results in
    following bugs:

    * since during second execution, parent of namespace node is unify, init of
      unify xlator fails.
    * even if init did not fail, re-execution of init in itself is bad, since it
      results in memory leaks etc. Worse, it can result in infinite recursive
      calls into init of unify node.

moved unify from 'cluster/unify' to 'legacy/cluster/unify'

2009-11-28T17:25:44+00:00

maintaining unify is not feasible, and its design of namespace is
not scalable too. hence moving it to 'legacy/' directory..

Thanks to unify, we learnt something about rename(). 'cluster/unify' has
served GlusterFS well for more than 2years, and its the time to say
goodbye :-(

unify getdents count reduced to 512 (from 1024)

2009-06-03T09:31:49+00:00

Thanks to Krishna  for pointing this out.

When a unify self-heal of large directory (directory with lot of entries)
is done, the getdents_cbk used to fail because of new limit of buffer size
(128KB). Noticed that earlier it used to streach upto 4MB, hence the value
1024 worked fine. By reducing it to 512, noticed, we can fit in well within
128KB limit, and hence unify self-heal goes through.

THIS: unify now uses xlator_notify for setting THIS
