  ndb - bug#18622
    Fix 4 replica bug in packLqhKeyReq, problem introduced by opt. nr.

  storage/ndb/src/kernel/blocks/dblqh/DblqhMain.cpp
    1.103 06/04/13 08:47:19 jonas@stripped +37 -15
    Fix packLqhKeyReqLab when having full AI in this and appending gci/rowid (used to casue 23+3 = 26 in signal length)
    Note: This is a very ineffectice patch, but only for 4 replicas
    This will be fixed when sending lqhkeyreq as long signal (or even just attrinfo as long)

# This is a BitKeeper patch.  What follows are the unified diffs for the
# set of deltas contained in the patch.  The rest of the patch, the part
# that BitKeeper cares about, is below these diffs.
