Subject: [PATCH 2/3] tpm: vtpm_proxy: Implement request_locality
Date: Mon, 17 Apr 2017 11:19:30 -0400 [thread overview]
Message-ID: <1492442371-30252-3-git-send-email-stefanb@linux.vnet.ibm.com> (raw)
In-Reply-To: <1492442371-30252-1-git-send-email-stefanb@linux.vnet.ibm.com>
Implement the request_locality function. Accept all localties assuming
that the emulator handling the localities will check for a valid locality.
