[LTP] [PATCH 1/1] ci: doc: Remove Ubuntu 16.04 LTS xenial

[Petr Vorel]

To keep number of CI jobs reasonable remove Ubuntu 16.04 LTS xenial.
The oldest distro is now openSUSE Leap 42.2 (the same kernel, glibc is
one release older, older gcc).

Hi,

anybody who wants to keep it please shout. But, please explain why
(openSUSE Leap 42.2 should satisfy testing old compilers).

Kind regards,
Petr
