Hi! Find below my second regression report for Linux 4.16. It lists 8
regressions I'm currently aware of.

To anyone reading this: Are you aware of any other regressions that got
introduced this development cycle? Then please let me know by mail (a
simple bounce or forward to the email address is enough!).

For details see http://bit.ly/lnxregtrackid And please tell me if there
is anything in the report that shouldn't be there.

Ciao, Thorsten

== Current regressions ==

Debian kernel package tool make-kpkg stalls indefinitely during kernel
build due to commit "kconfig: remove check_stdin()"
Status: stalled after some discussions; seems nobody really cares deeply?
Note: From the discussion: "Shouldn't be a problem to back this one out
either if it turns out to cause massive amounts of pain in practice I
guess, even if it's the Debian tools doing something weird."
