Subject: [v4.17-rc5][bisected] be83bbf80682 breaks /proc/vmcore mmap
Date: Sat, 19 May 2018 05:15:22 +0200 [thread overview]
Message-ID: <cover.thread-4f3684.your-ad-here.call-01526696764-ext-9375@work.hours> (raw)
Greetings,
be83bbf80682 "mmap: introduce sane default mmap limits" introduced a
problem with mapping /proc/vmcore if it is bigger than 2gb. This
breaks s390 kernel zfcpdump. But it should be a general problem.
Please consider the following one-liner fix, if it makes sense.
