From 05c900ce7392ef2f0bc7647863c8680641e137df Mon Sep 17 00:00:00 2001 From: Vitaly Kuznetsov Date: Thu, 22 Apr 2021 18:11:23 +0200 Subject: [PATCH] i386: adjust the expected KVM_GET_SUPPORTED_HV_CPUID array size SYNDBG leaves were recently (Linux-5.8) added to KVM but we haven't updated the expected size of KVM_GET_SUPPORTED_HV_CPUID output in KVM so we now make serveral tries before succeeding. Update the default.
