Hi Avri,

As promised, this is v2 of the patch series that simplifies and optimizes the
UFS driver. These patches are entirely untested. Any feedback is welcome.

Thanks,

Bart.

  Allow SCSI LLDs to reserve block layer tags
  ufs: Use reserved tags for TMFs
  ufs: Avoid busy-waiting by eliminating tag conflicts
  ufs: Use blk_{get,put}_request() to allocate and free TMFs
  ufs: Simplify the clock scaling mechanism implementation
