I tested with the latest kernel of branch 4.4 available on kernel.org
which is 4.4.52.
I see the exact same behavior. The cifs module is the same version as
the one shipped with Xenial's kernel. Therefore I am setting the tag
kernel-bug-exists-upstream as you suggested.
Thank you.

Confirmed

Bug description:
This seems to be a kernel bug affecting cifs modules => 2.06.
This might be fixed by the upstream kernel provider but I need it
fixed in the specific kernel version that Ubuntu ships.

This behavior is not reproducible in trusty (see the attached files), nor in
CentOS 6, and early CentOS 7, I see this behavior on cifs module => 2.06.
