+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).
