Sage Weil e18001c11b mds: fix stray replica push on _rename_prepare_witness() 
We need to push all parents of the straydn to the target.  This changed
a while back with the mdsdir stuff but this bit of code wasn't updated.
Updated to mirror send_dentry_unlink().

This fixes a crash like:
mds/MDCache.cc: In function 'void MDCache::adjust_subtree_auth(CDir*, std::pair<int, int>, bool)':
mds/MDCache.cc:644: FAILED assert(root)
 ceph version 0.22~rc (0e67718a36)

Ceph - a scalable distributed file system
-----------------------------------------

Please see http://ceph.newdream.net/ for current info.

----

To build the server daemons, and FUSE client,

$ ./autogen.sh
$ ./configure

$ make
 or
$ cd src
$ make

(Note that the FUSE client will only be built if libfuse is present.)

----

A quick summary of binaries that will be built in src/

daemons:
 cmon -- monitor daemon.  handles cluster state and configuration
         information.
 cosd -- storage daemon.  stores objects on a given block device.
 cmds -- metadata daemon.  handles file system namespace.
 ceph -- send management commands to the monitor cluster.

userland clients:
 cfuse -- fuse client.
 csyn -- synthetic workload generator client.

tools:
 monmaptool -- create/edit mon map
 osdmaptool -- create/edit osd map 
 crushtool -- create/edit crush map

scripts:
 mkcephfs -- cluster mkfs tool
 init-ceph -- init.d start/stop script
