ceph: more accurate statfs

2017-09-06T17:56:49+00:00

Improve accuracy of statfs reporting for Ceph filesystems comprising
exactly one data pool. In this case, the Ceph monitor can now report
the space usage for the single data pool instead of the global data
for the entire Ceph cluster. Include support for this message in
mon_client and leverage it in ceph/super.

ceph: new cap message flags indicate if there is pending capsnap

2017-09-06T17:56:44+00:00

These flags tell mds if there is pending capsnap explicitly.
Without this explicit notification, mds can only conclude if
client has pending capsnap. The method mds use is inefficient
and error-prone.

libceph: make RECOVERY_DELETES feature create a new interval

2017-08-01T14:46:45+00:00

This is needed so that the OSDs can regenerate the missing set at the
start of a new interval where support for recovery deletes changed.

libceph: fix old style declaration warnings

2017-07-17T12:54:58+00:00

The new macros don't follow the usual style for declarations,
which we get a warning for with 'make W=1':

In file included from fs/ceph/mds_client.c:16:0:
include/linux/ceph/ceph_features.h:74:1: error: 'static' is not at beginning of declaration [-Werror=old-style-declaration]

This moves the 'static' keyword to the front of the
declaration.

libceph: advertise support for NEW_OSDOP_ENCODING and SERVER_LUMINOUS

2017-07-07T15:26:24+00:00

All four SERVER_LUMINOUS feature bits are implemented, switch it on!

NEW_OSDOP_ENCODING doesn't mean much for the client (it signifies
support for MOSDOp v6) but needs to be enabled in order to get the
latest (currently v25) pg_pool_t.

libceph: pg_upmap[_items] infrastructure

2017-07-07T15:25:18+00:00

pg_temp and pg_upmap encodings are the same (PG -> array of osds),
except for the incremental remove: it's an empty mapping in new_pg_temp
for pg_temp and a separate old_pg_upmap set for pg_upmap.  (This isn't
to allow for empty pg_upmap mappings -- apparently, pg_temp just wasn't
looked at as an example for pg_upmap encoding.)

Reuse __decode_pg_temp() for decoding pg_upmap and new_pg_upmap.
__decode_pg_temp() stores into pg_temp union member, but since pg_upmap
union member is identical, reading through pg_upmap later is OK.
