From 3c71ae8ec9adde96f5ecfcbeef62ccf1d420f83f Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Wed, 18 Mar 2026 15:47:05 -0300 Subject: tools headers UAPI: Sync linux/kvm.h with the kernel sources To pick the changes in: da142f3d373a6dda ("KVM: Remove subtle "struct kvm_stats_desc" pseudo-overlay") That just rebuilds perf, as these patches don't add any new KVM ioctl to be harvested for the 'perf trace' ioctl syscall argument beautifiers. This addresses this perf build warning: Warning: Kernel ABI header differences: diff -u tools/include/uapi/linux/kvm.h include/uapi/linux/kvm.h Please see tools/include/uapi/README for further details.
