Hi there, Is perhaps a fix for disabling overlayfsroot for filesystems with revalidate on the horizon? My use case for overlayfs is a NFS (v3 or v4) lowerdir, which appears rejected by the code below because NFS defines d_revalidate, d_automount, and d_weak_revalidate (v3 only). There has been discussion in this launchpad bug about xattr copyup problems: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1039402 fs/overlayfs/super.c@692: /* * We don't support: * - automount filesystems * - filesystems with revalidate (FIXME for lower layer) * - filesystems with case insensitive names */ if (dop && (dop->d_manage || dop->d_automount || dop->d_revalidate || dop->d_weak_revalidate || dop->d_compare || dop->d_hash)) { return false; } Regarding the referenced code in overlayfs-next, is there a condition in which NFSv4 could be supported, such as if mounted read-only? -Blake -- To unsubscribe from this list: send the line "unsubscribe linux-unionfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
