libceph: eliminate sparse warnings

2013-02-25T21:37:18+00:00

Eliminate most of the problems in the libceph code that cause sparse
to issue warnings.
    - Convert functions that are never referenced externally to have
      static scope.
    - Pass NULL rather than 0 for a pointer argument in one spot in
      ceph_monc_delete_snapid()

This partially resolves:

libceph: Fix sparse warning

2012-10-01T19:30:49+00:00

Make ceph_monc_do_poolop() static to remove the following sparse warning:
 * net/ceph/mon_client.c:616:5: warning: symbol 'ceph_monc_do_poolop' was not
   declared. Should it be static?
Also drops the 'ceph_monc_' prefix, now being a private function.

libceph: delay debugfs initialization until we learn global_id

2012-08-20T17:03:15+00:00

The debugfs directory includes the cluster fsid and our unique global_id.
We need to delay the initialization of the debug entry until we have
learned both the fsid and our global_id from the monitor or else the
second client can't create its debugfs entry and will fail (and multiple
client instances aren't properly reflected in debugfs).

libceph: revoke mon_client messages on session restart

2012-07-31T01:16:40+00:00

Revoke all mon_client messages when we shut down the old connection.
This is mostly moot since we are re-using the same ceph_connection,
but it is cleaner.

libceph: initialize mon_client con only once

2012-07-06T04:14:38+00:00

Do not re-initialize the con on every connection attempt.  When we
ceph_con_close, there may still be work queued on the socket (e.g., to
close it), and re-initializing will clobber the work_struct state.

libceph: set peer name on con_open, not init

2012-07-06T04:14:35+00:00

The peer name may change on each open attempt, even when the connection is
reused.

libceph: flush msgr queue during mon_client shutdown

2012-06-15T18:26:40+00:00

We need to flush the msgr workqueue during mon_client shutdown to
ensure that any work affecting our embedded ceph_connection is
finished so that we can be safely destroyed.

Previously, we were flushing the work queue after osd_client
shutdown and before mon_client shutdown to ensure that any osd
connection refs to authorizers are flushed.  Remove the redundant
flush, and document in the comment that the mon_client flush is
needed to cover that case as well.

libceph: make ceph_con_revoke() a msg operation

2012-06-06T14:23:54+00:00

ceph_con_revoke() is passed both a message and a ceph connection.
Now that any message associated with a connection holds a pointer
to that connection, there's no need to provide the connection when
revoking a message.

This has the added benefit of precluding the possibility of the
providing the wrong connection pointer.  If the message's connection
pointer is null, it is not being tracked by any connection, so
revoking it is a no-op.  This is supported as a convenience for
upper layers, so they can revoke a message that is not actually
"in flight."

Rename the function ceph_msg_revoke() to reflect that it is really
an operation on a message, not a connection.
