[PATCH 5.13 073/104] KVM: selftests: Fix missing break in dirty_log_perf_test arg parsing
From: Greg Kroah-Hartman
Date: Mon Aug 02 2021 - 10:13:32 EST
From: David Matlack <dmatlack@xxxxxxxxxx>
[ Upstream commit 15b7b737deb30e1f8f116a08e723173b55ebd2f3 ]
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")
