[GIT PULL] XFS update for 3.0-rc4

[Alex Elder]

Linus, please pull the following two XFS changes for 3.0.

The first is a simple fix that flips the sign of an error return
value.

The second fixes a bug having to do with the order in which log and
data (or realtime) device cache flushes are issued.  This could lead
to data corruption when an external log was used.  Previously, we
avoided the problem by disabling barriers and issuing a warning
about that at mount time, but the recent barrier/FUA rework makes
that not work properly any more.  Fixing the flush ordering problem
also nicely eliminates the need a block of code.

Thanks.
