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.
