Not sure if it's the reason why Samba uses it, but many portable applications use statvfs because that is the standardizes one in XPG / recent Posix while statfs is just a BSD extension Linux picked up. So making sure statvfs goes fast is a pretty essential thing. -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
