Subject[PATCH 0/1] random vs blk-mq
A tester found out that we need add_disk_randomness for my scsi-mq
branch. The patch applied exports add_disk_randomness so that modular
scsi still works with a driver that either uses the low-level I/O
completion routines for the old block layer, or blk-mq, and I'd love
to get this in through Jens' tree which has all the other block work
scsi-mq requires.

But this also brings up an interesting question: blk-mq currently
does not set QUEUE_FLAG_ADD_RANDOM in the default queue flags, so
simply converting a driver to blk-mq will mean it stops contributing
to the random pool. Do we need a more fine grained way to control
this, especially for SCSI?
