[PATCH v2 5/6] KVM: selftests: Fix missing break in dirty_log_perf_test arg parsing

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
