Hi Martin,

A bug was opened against the Ubuntu kernel[0].  After a kernel bisect,
it was found that reverting the following commit resolved this bug:

commit 66c28f97120e8a621afd5aa7a31c4b85c547d33d
Author: Martin K. Petersen <martin.petersen@oracle.com>

    [SCSI] sd: Update WRITE SAME heuristics


The regression was introduced as of v3.11-rc1, but it also made it's way
into the stable trees.

I see that you are the author of this patch, so I wanted to run this by
you.  I was thinking of requesting a revert for v3.12, but I wanted to
get your feedback first.


Thanks,

Joe
