Revision 15b7b737deb30e1f8f116a08e723173b55ebd2f3 authored by David Matlack on 13 July 2021, 22:09:56 UTC, committed by Paolo Bonzini on 27 July 2021, 20:58:59 UTC
There is a missing break statement which causes a fallthrough to the next statement where optarg will be null and a segmentation fault will be generated. Fixes: 9e965bb75aae ("KVM: selftests: Add backing src parameter to dirty_log_perf_test") Reviewed-by: Ben Gardon <bgardon@google.com> Signed-off-by: David Matlack <dmatlack@google.com> Message-Id: <20210713220957.3493520-6-dmatlack@google.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
