Subject: [PATCH 3/4] Revert "KVM: selftests: Test slot move/delete with slot zap quirk enabled/disabled"
Date: Thu, 26 Sep 2024 17:16:34 -0700	[thread overview]
Message-ID: <20240927001635.501418-4-seanjc@google.com> (raw)
In-Reply-To: <20240927001635.501418-1-seanjc@google.com>

Revert set_memory_region_test's KVM_X86_QUIRK_SLOT_ZAP_ALL testcase, as
the quirk is being removed, i.e. the KVM side of things is being reverted.

This reverts commit b4ed2c67d275b85b2ab07d54f88bebd5998d61d8.
