osdmap: allow blacklist of an entire ip
We can backlist either a specific instance (1.2.3.4:1234/5678) or an
entire IP, in which case the table has something like "1.2.3.4:0/0" (a port
and nonce of 0).

mon: handle subscribe to osdmap=1
We would send an incremental for anything >1, or the latest map, but not
osdmap e1 itself. Fix the condition, and make send_incremental() smart
about starting with the full map at 1 as needed.

mds: fix journal replay of session close->open after reconnect
If the client reconnects, the journal 'close' replay doesn't remove the
session, which leaves the session state intact. It needs to reset it in
that case, or else we get problems if the session is reopened and the
state doesn't match up.

osd: always mark down old hb peers; send map update via cluster link
If we don't mark down the hb link immediately, we'll forget about it
because it won't be in the from or to set anymore, and if it does go down
later we'll end up with garbage in the logs.
Instead, always mark it down. Since we want to share our map with old
peers that are still up, do that via the cluster link instead, which is
reliably marked down if/when the peer goes down.

crush: return error instead of BUGing on bad forcefed mapping
The forcefed mapping relies on a parent map. However, the current
implementation assumes that the parent mapping is unique for all rules. If
that is not the case (i.e., some osd exists in multiple hierarchies) then
we cannot assert that the TAKE matches the calculated force_context.
For now, we can just fail the mapping in that case (we don't use forcefed
mappings yet). The real solution is probably to define parent maps for
all possible hierarchies (i.e., starting at each unique TAKE starting
point).

mds: fix ENOTEMPTY checking on rmdir/rename
We can't trust the inode rstat size without holding the locks. We can
look at our auth frags and though without fear of a false positive
ENOTEMPTY, however.
Rename the function, introduce a helper for the locked check, update
comments, etc.

Hi,
I just realized librados.hpp could compile only if "using namespace
std;" is declared before "#include <rados/librados.hpp>", because
"vector" used without std namespace, and I think it's wrong.
It can fix following patch.

mds: fix cap encoding skipping when snaprealm differs
We were avoiding adding a new cap, but _any_ issue is problematic, not just
adds (which we can't really be sure about anyway due to races with client
cap release).
The only thing I've found, is that the *.so files are included in the -devel
rpm. This leads to the fact that the 'find' in cclass doesn't return any
files. I'd suggest the attached change in the script.

from debian policy:

This is used to declare that one package may be more useful with one or more
others. Using this field tells the packaging system and the user that the listed

that installing this one without them is perfectly reasonable.
