Subject: [PATCH v4 17/17] perf: Drop guest callback (un)register stubs
Date: Thu, 11 Nov 2021 02:07:38 +0000 [thread overview]
Message-ID: <20211111020738.2512932-18-seanjc@google.com> (raw)
In-Reply-To: <20211111020738.2512932-1-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.
