The tag allocation is limited by the number of active queues and a

UFS devices have multiple logical units, and they can limit the depth of
data LUNs by the fair tag sharing algorithm. Make the fair tag sharing
configurable and improve the performance for UFS devices.

Hi Jens,

This patch series is slightly more complicated than the patch that I posted in January. Do you prefer the approach of this patch series or rather the approach of the patch that I posted in January?

Thank you,

Bart.
