Following sequence of events can happen.
- Client releases an inode, queues cap release message.
- A 'lookup' reply brings the same inode back, but the reply
doesn't contain xattrs because MDS didn't receive the cap release
message and thought client already has up-to-data xattrs.
The fix is force sending a getattr request to MDS if xattrs_version is 0.
The getattr mask is set to CEPH_STAT_CAP_XATTR, so MDS knows client does
not have xattr.

client to differentiate no xattr in inode from MDS skips sending xattr

osd: subscribe to the newest osdmap when reconnecting to a monitor
This is mostly relevant in testing clusters, but it ensures that an OSD
disconnecting from the monitor at the wrong time will still see any recent

osdc/Objecter: fix command op cancellation race
Cancel the command op timeout event before we clear out the op from the
session struct. This isn't strictly necessary because command_op_cancel
will "gracefully" handle the case where the tid is no longer present, but
this avoids that noise and is cleaner.

mds: limit number of caps inspected in caps_tick
This is to avoid hitting an O(caps) loop in the worst
cast scenario. This mechanism is a little crude but
should be superceded at some point by admin socket
functionality to inspect session caps so that we
don't need to spit out this level of detail in logs.

client: more precise cap trimming
Two fixes:
* Client would unlink everything it could, instead of just
meeting its goal, because caps.size() doesn't change until
dentries are cleaned up later. Take account of the trimmed
count in the while() condition to fix that.
* Don't count the root ino as trimmed, as although it has no
dentries (of course), we will never give up the cap.
With this change, the client will now precisely achieve the number
of caps requested in CEPH_SESSION_RECALL_STATE messages.

client: fix crash in trim_caps
In a75af4c2, procedure was added to invalidate root's dentries
if the trimming failed to free enough caps. This would sometimes
crash because root->dir wasn't necessarily open.
Fix by only doing it if root dir is open, though I suspect this
may not be the end of it...

init-radosgw.sysv: Support systemd for starting the gateway
When using RHEL7 the radosgw daemon needs to start under systemd.
Check for systemd running on PID 1. If it is then start
the daemon using: systemd-run -r <cmd>. pidof returns null
as it is executed too quickly, adding one second of sleep and
script reports startup correctly.
The plugins are made a sub-section of the erasure code profile
section. The k and m parameters are removed from erasure code profile
documentation. They were added for simplicity in the first version
because there was only one plugin. But they should really be in the
plugin documentation.
