Subject: Re: [PATCH 1/2] arch: mark syscall number 435 reserved for clone3
Date: Mon, 15 Jul 2019 15:56:04 +0200	[thread overview]
Message-ID: <e14eb2f9-43cb-0b9d-dec4-b7e7dcd62091@de.ibm.com> (raw)
In-Reply-To: <20190714192205.27190-2-christian@brauner.io>

I think Vasily already has a clone3 patch for s390x with 435.
