Martin K. Petersen 0e0a4da352 Merge patch series "scsi: ufs: Remove overzealous memory barriers"
Andrew Halaney <ahalaney@redhat.com> says:

Please review with care as I'm not all that confident in this subject.
UFS has a lot of mb() variants used, most with comments saying "ensure
this takes effect before continuing". mb()'s aren't really the way to
guarantee that, a read back is the best method.

Some of these though I think could go a step further and remove the
mb() variant without a read back. As far as I can tell there's no real
reason to ensure it takes effect in most cases (there's no delay() or
anything afterwards, and eventually another readl()/writel() happens
which is by definition ordered). Some of the patches in this series do
that if I was confident it was safe (or a reviewer pointed out prior
that they thought it was safe to do so).

Thanks in advance for the help,
Andrew
