Subject: [kvm-unit-tests PATCH 2/2] x86: remove use of compiler's memset from emulator.c
Date: Mon, 10 May 2021 18:50:16 -0700 [thread overview]
Message-ID: <20210511015016.815461-2-jacobhxu@google.com> (raw)
In-Reply-To: <20210511015016.815461-1-jacobhxu@google.com>
Per Sean in discussion of the previous patch, "using the compiler's
memset() in kvm-unit-tests seems inherently dangerous since the tests
are often doing intentionally stupid things."
The string.h memset is already imported through libcflat.h, so let's use
that instead.
