For the 1st commit, the commit message says:
Within ctdb_daemon_read_cb the provided data is checked for sanity,
e.g. correct size and content. This is not required because it was
done already by the caller.
You might as well name the caller.
I assume you mean queue_process() in ctdb/common/ctdb_io.c. However, I
don't see where that function confirms that it has read a full
In the 2nd commit, since the debug message is very generic and is meant
for debugging, please use DBG_DEBUG(), since this logs the function
name, instead of D_DEBUG().
We introduced the D_*() macros for CTDB because we do a lot of logging
of cluster/node state changes. These messages are usually unique and
are often meant to be read by an admin or support person, so don't need
the clutter of the function name. For the deeper debugging messages we
need a little more context.
I think the 3rd commit looks good.
peace & happiness,
