f00546fee0 doc/cephfs: add note about deletion from OSD restricted pool 
As described in http://tracker.ceph.com/issues/17937, a client with
restricted pool access can still delete files unless a corresponding
MDS path restriction is also in place.

mds: remove max_mds config option 
It is now required that all changes to max_mds use the run-time `ceph fs
set max_mds` command. The rationale for this change is that it is
confusing to have a configuration for max_mds which is only observed at
file system creation.

b6d2b6d1a5 client: report root's quota in statfs 
When user is mounted a quota-restricted inode
as the root, report that inode's quota status
as the filesystem statistics in statfs.

This allows us to have a fairly convincing illusion
that someone has a filesystem to themselves, when
they're really mounting a restricted part of
the larger global filesystem.
