Subject: Re: [PATCH v2] fs: introduce pipe-only dump mode suid_dumpable=3

> This patch introduces suid_dumpable=3 to allow privilege-changed
> processes to be dumped only to a pipe handler (and not directly to
> disk). The value of suid_dumpable=2 is now deprecated, and attempting
> to set this sysctl value returns -EINVAL.
