Sage Weil 3941ee2e77 mds: adjust rdlock forwarding on replicas 
Include LOCK, MIX, and associated gather states.  An EXCL on the
auth (which is not temporary) is a LOCK on the replica, so fw.
(Otherwise we'd need another state.)  MIX should fw too, since
it is also stable and the replcia can't rdlock.

Include leading states because rdlock waits for WAIT_RD, not
stable.

README 

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

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

----

To build the Linux kernel client,

$ cd src/kernel
$ make
or
$ make KERNELDIR=/path/to/linux
$ insmod ceph.ko
$ mount -t ceph 1.2.3.4:/ /mnt/ceph
...

----

To build the server daemons, and FUSE client,

$ ./autogen.sh
$ ./configure
$ 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.
 cmonctl -- send commands to the monitor cluster.

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

tools:
 mkmonfs -- create a fresh monfs (for a new filesystem)
 monmaptool -- create/edit mon map
 osdmaptool -- create/edit osd map 
 crushtool -- create/edit crush map
 dupstore -- duplicate an osd object store (offline)

development/debugging:
 fakesyn -- simulator with synthetic workload
 fakefuse -- simulator that mounts with fuse
