Since you marked this for -stable, just a heads-up that the previous patch for the data exposure was rejected from -stable (see [1]) because it has the mismatching "!IS_NOQUOTA(inode) &&" line, which didn't exist until 4.6. I removed it locally but Greg probably wants an official patch. So both this and the previous patch need to be submitted. -h [1] http://permalink.gmane.org/gmane.linux.kernel.stable/18074{4,5,6} -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
