Bug#900821: linux-image-4.9.0-6-amd64: apache reads wrong data over cifs filesystems served by samba

[Stefan Fritsch <sf@sfritsch.de>]

Hi,

by default, apache uses mmap, so probably mmap is broken on cifs. An
alternate workaround should be to set EnableMMAP off in the apache
config.

Cheers,
Stefan
