Add a description of max_file_size to the CephFS admin docs.
Thanks to John Spray <jspray@redhat.com> on ceph-users for this
information.

The "session ls" and "session evict" are now
"client ls" and "client evict" (the old ones
are still there for backwards compatibility).
The automatic client eviction now emits
cluster logs that call the client by its
friendly name (usually the hostname).

This makes the code a bit awkward because we now have
4x paths through this function (blocking, noblocking, blacklisting,
nonblacklisting).

This was occasionally useful for establishing a journal-less
performance baseline, but it has two big problems:
* We don't test it, so it's probably broken a lot of the time
* It sounds a lot to a naive user like an option for controlling
logging.
IMO, anyone who wants this behaviour is in sufficiently advanced
territory that then can hack it in and recompile, we don't need
to leave dangerous things like this in our releases.

This allows the client/admin to pin a directory tree to a particular rank,
preventing its export by the dynamic balancer.

This had been broken for some time, as since the new
JournalStream stuff, zero padding was no longer a valid
encoding.

Client.cc marks session as stale instead of reconecting after received
reset from MDS. On MDS side session is closed so MDS is ignoring cap
renew. This adds option to reconnect stale client sessions instead of
just marking sessions stale.

Add a procedure that permits reconstructing metadata in a potentially
damaged cephfs metadata pool and writing the results into a
freshly-initialized pool that refers to the same data pool. Add option
flags to override checks that would ordinarily prevent this and add
options to the recovery tools to write output to a separate pool instead of
the one selected for recovery. See docs/cephfs/disaster-recovery.rst for
details.

Rewrote mount.fuse.ceph to move ceph-fuse options to `fs_mntops`, where it should be.
Bash version with options in `fs_spec` is counterintuitive and cause issues in some
situations (systemd, for example)

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.
