Sorry for resurrecting this old thread, but I'm experiencing this very same
issue.
 
I'm observing this in a Debian Jessie (kernel 3.16.7) box, so my guess is
that the issue was never solved in the systemd part (I'm using version
215-17+deb8u4). Can anyone confirm this?

Also, regarding the disable of CONFIG_FHANDLE, how would I do that? Should I
set CONFIG_FHANDLE=n and recompile the kernel (with aufs)? When I tried that
I got this error:

fs/built-in.o: In function `aufs_encode_fh':
/home/sgimeno/kernel-patches/linux-backports/fs/aufs/export.c:752: undefined
reference to `exportfs_encode_fh'
fs/built-in.o: In function `decode_by_path':
/home/sgimeno/kernel-patches/linux-backports/fs/aufs/export.c:518: undefined
reference to `exportfs_decode_fh'
Makefile:893: recipe for target 'vmlinux' failed

... so I think it must be something else.

Any help would be appreciated!!

Best regards,

Santiago
