Joe Thornber 9d1b404cbc dm cache policy smq: distribute entries to random levels when switching to smq
For smq the 32 bit 'hint' stores the multiqueue level that the entry
should be stored in.  If a different policy has been used previously,
and then switched to smq, the hints will be invalid.  In which case we
used to put all entries in the bottom level of the multiqueue, and then
redistribute.  Redistribution is faster if we put entries with invalid
hints in random levels initially.
