Hi Martin,

While reading the UFS source code I noticed that some existing mechanisms
are duplicated in this driver. These patches simplify and optimize the UFS
driver. These patches are entirely untested.

Bart.

  ufs: Avoid busy-waiting by eliminating tag conflicts
  ufs: Simplify the clock scaling mechanism implementation
  ufs: Remove the SCSI timeout handler
  ufs: Remove superfluous memory barriers

Please allow few more days to test it.

Thanks,

Thank you Avri for having offered to test this patch series. Please wait 
with testing until I have posted v2 of this series - I just realized 
that patch 2/4 needs more work.

Thanks,

Bart.
