A constant reminder of how > broken this is. Exposing the subvolume id also makes this somewhat redundant. There is a upcoming potential problem where even the 64-bit field I placed in statx() may be insufficient. The Auristor AFS server, for example, has a 96-bit vnode ID, but I can't properly represent this in stx_ino. Currently, I just truncate the value to fit and hope that the discarded part will be all zero, but that's not really a good thing to do - especially when stx_ino is used programmatically to check for hardlinks. Would it be better to add an 'stx_ino_2' field and corresponding flag? David
