Do you suppose you could look at what blktrace says is going down? If you could compare what blktrace says is going to the bcache device with and without XFS, hopefully that'll show what's going wrong... Only thing I can think of that would cause it is for some reason XFS is sending bios down in the wrong order... which normally wouldn't be _too_ painful since both the elevator and the disk's cache will reorder the IOs, so I can see how that would slip by. -- To unsubscribe from this list: send the line "unsubscribe linux-bcache" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
