/sbin/umount.aufs:br.c:47: internal error, [mount point]: Inappropriate ioctl for device

[Cănărău C. <can...@ya...>]

Hi!

I am using Gentoo Linux and since version 20140721 umount.aufs it is broken.
Error message is: /sbin/umount.aufs:br.c:47: internal error,
/usr/portage: Inappropriate ioctl for device

I am compressing portage usinf squashfs and using in with squashmount
for write/changes mode (sorry for my poor English).

Mount point and options:
/usr/portage.sqfs on /usr/portage.readonly type squashfs (ro,noatime)
aufs on /usr/portage type aufs (rw,noatime,si=31461772857100b7)
/var/db.sqfs on /var/db.readonly type squashfs (ro,noatime)
aufs on /var/db type aufs (rw,noatime,si=314617754bfb90b7)
