From: Sean Christopherson Date: Thu, 11 Nov 2021 02:07:38 +0000 (+0000) Subject: perf: Drop guest callback (un)register stubs X-Git-Tag: v5.17-rc1~98^2 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=a9f4a6e92b3b319296fb078da2615f618f6cd80c;p=thirdparty%2Fkernel%2Flinux.git perf: Drop guest callback (un)register stubs 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.
