It doesn't perform the xattr read on _every_ lookup, but only when the object has a special set of permission bits. But actually, it probably doesn't need that 'type" attribute check at all. It should delegate that check to mountd. I assume many of those upcalls would hit in the export cache anyway? -- Chuck Lever chuck[dot]lever[at]oracle[dot]com -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
