FYI, I sent a patch for the zero S/G length issue. With this xfstests does fine for ext4 and btrfs. With XFS I still run into corruption warnings for the slab use after free poison pattern. I suspect that issue might be related to uniqueue XFS I/O patterns. One thing that might be related is that XFS can submit bios backed by kmalloced memory. I've also tested XFS on various other storage devices on the same kernel and didn't see an issue like that just to be sure. -- To unsubscribe from this list: send the line "unsubscribe target-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
