Subject: [PATCH v3 16/16] perf: Drop guest callback (un)register stubs
Date: Tue, 21 Sep 2021 17:05:33 -0700	[thread overview]
Message-ID: <20210922000533.713300-17-seanjc@google.com> (raw)
In-Reply-To: <20210922000533.713300-1-seanjc@google.com>

Drop perf's stubs for (un)registering guest callbacks now that KVM
registration of callbacks is hidden behind GUEST_PERF_EVENTS=y.  The only
other user is x86 XEN_PV, and x86 unconditionally selects PERF_EVENTS.

No functional change intended.
