Why it was needed to invent a new flag instead of just clear BLK_MQ_F_TAG_QUEUE_SHARED?
Hi Avri, The meaning of BLK_MQ_F_TAG_QUEUE_SHARED is "the tag set is shared across multiple request queues". Clearing BLK_MQ_F_TAG_QUEUE_SHARED if the tag set is shared would be wrong: it would break all the code outside the tag allocation code that tests this flag. Thanks, Bart.
