+From: "Jan (janneke) Nieuwenhuizen" <janneke@gnu.org>
+Date: Tue, 12 May 2020 07:39:59 +0200
+Subject: [PATCH] ext2fs: Update to upstream Hurd-reserved xattr index for
+ "gnu.*".
+
+See
+    https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=3980bd3b406addb327d858aebd19e229ea340b9a
+
+This supports setting (and reading) of passive trasnlators from
+GNU/Linux, e.g.
+
+    dd if=/dev/zero of=file bs=1k count=1000
+    losetup /dev/loop0 file
+    mke2fs -t ext2 -o hurd -O ext_attr /dev/loop0
+    mount -t ext2 -o x-xattr-translator-records /dev/loop0 /mnt
+    mkdir -p /mnt/servers/socket
+    touch /mnt/servers/socket/1
+    setfattr --name=gnu.translator --value='/hurd/pflocal\0' /mnt/servers/socket/1
+    getfattr --name=gnu.translator /mnt/servers/socket/1
+    # file: 1
+    gnu.translator="/hurd/pflocal"
+
+* ext2fs/xattr.c (struct _xattr_prefix): For "gnu.*", use index for
+the Hurd (10).
