      "message": "ceph: explicitly specify page alignment in network messages\n\nThe alignment used for reading data into or out of pages used to be taken\nfrom the data_off field in the message header.  This only worked as long\nas the page alignment matched the object offset, breaking direct io to\nnon-page aligned offsets.\n\nInstead, explicitly specify the page alignment next to the page vector\nin the ceph_msg struct, and use that instead of the message header (which\nprobably shouldn\u0027t be trusted).  The alloc_msg callback is responsible for\nfilling in this field properly when it sets up the page vector.\n\nSigned-off-by: Sage Weil \u003csage@newdream.net\u003e\n"
