Sage Weil 67533e1443 client: be more careful with FILE_BUFFER cap refs 
We should either hold a ref or not; whether we release one can't depend on
whether one is held because we can't assume the ref belongs to us.

This changes the fix in cf6b1de4 so that the ObjectCacher just calls the
flush callback if it happens to trim all dirty buffers.

We also drop the (bogus) assert about the number of refs held.

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
