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).
