'lookup-unhashed' option of distribute should be 'auto' by default.

2010-02-06T16:44:17+00:00

* Added 'auto' option, older boolean options works as they used to.

* This option should make 'create' rate faster, also handles
  self-healing of linkfile properly in case of scaling to
  more servers or filesystem is getting full.

dht: initialize layout type

2010-01-23T19:07:05+00:00

Instead of relying on CALLOC's zero initialization which happens
to be the value of DHT_HASH_TYPE_DM, explicitly set the value

distribute: Dont dereference sbuf on failed readlink_cbk

2009-12-18T16:41:33+00:00

This fixes a crash that was caused due to a NULL pointer deref
because a NULL sbuf is returned if the readlink fop fails.
