[PATCH 1/4] filter: latest mkfs.xfs makes logical sector size noise

[Dave Chinner <david@fromorbit.com>]

From: Dave Chinner <dchinner@redhat.com>

On devices that have a logical sector smaller than physical sector,
this extra, harmless output now occurs:

     QA output created by 060
    +specified blocksize 1024 is less than device physical sector size 4096
    +switching to logical sector size 512
     Creating directory system to dump using src/fill.
     Setup .......................................
     Dumping to files...

And it causes lots of tests to fail unnecessarily. Filter it.
