From: Michael Jeanson Date: Tue, 14 Dec 2021 20:06:51 +0000 (-0500) Subject: fix: KVM: MMU: change tracepoints arguments to kvm_page_fault (v5.16) X-Git-Tag: v2.12.7~3 X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=5d252a9544cf27c222ab232a8875a4cdb3d920f1;p=lttng-modules.git fix: KVM: MMU: change tracepoints arguments to kvm_page_fault (v5.16) See upstream commit : commit f0066d94c92dc5cf7f1a272a1bd324b0fc575292 Author: Paolo Bonzini Date: Fri Aug 6 04:35:50 2021 -0400 KVM: MMU: change tracepoints arguments to kvm_page_fault Pass struct kvm_page_fault to tracepoints instead of extracting the arguments from the struct. This also lets the kvm_mmu_spte_requested tracepoint pick the gfn directly from fault->gfn, instead of using the address.
