980a07380d document the write / read path for erasure encoding 
Explains how objects are stored and used in erasure coded pools. It is
the result of discussions that occured on the ceph-devel mailing list
around june 2013. The rationale behind each change can be found in the
archive of the mailing list. For instance, the coding of the chunk
number with the object or the decision to decode using any K chunks
instead of trying to fetch the data chunks when possible because it
would allow simple concatenation when systematic codes are used.

dbddffef06 update op added to a waiting queue or discarded 
The decision to discard an op happens either in OSD or in PG.
The operation queue goes to a single OpWQ object if waiting_map does not impose a delay op_queue.
The decision to add an op to a waiting queue regardless of its type is updated.
The decision to add a CEPH_MSG_OSD_OP to a waiting queue is described in full.
