Ceph is a distributed object, block, and file storage platform

This gives us a pointer to the position into the list where the final length value will be copied. Previously we used bl.copy_in(), which takes a byte offset and needs iterator over the bufferlist to seek to the correct position, resulting in O(n^2) encoding time for large structures.

-----------------------------------------
Please see http://ceph.newdream.net/ for current info.
----
To build the server daemons, and FUSE client,
$ ./autogen.sh
$ ./configure
$ 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:
ceph-mon -- monitor daemon. handles cluster state and configuration
information.
ceph-osd -- storage daemon. stores objects on a given block device.
ceph-mds -- metadata daemon. handles file system namespace.
ceph-fuse -- fuse client.
tools:
ceph -- send management commands to the monitor cluster.
rados -- interact with the object store
rbd -- manipulate rados block device images
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
