Subject: [PATCH AUTOSEL 6.3 02/18] KVM: selftests: Add 'malloc' failure check in vcpu_save_state
Date: Tue,  9 May 2023 17:19:10 -0400	[thread overview]
Message-ID: <20230509211928.21010-2-sashal@kernel.org> (raw)
In-Reply-To: <20230509211928.21010-1-sashal@kernel.org>

From: Ivan Orlov <ivan.orlov0322@gmail.com>

[ Upstream commit 735b0e0f2d001b7ed9486db84453fb860e764a4d ]

There is a 'malloc' call in vcpu_save_state function, which can
be unsuccessful. This patch will add the malloc failure checking
to avoid possible null dereference and give more information
about test fail reasons.
