Subject: [PATCH 05/10] KVM: SVM: Annotate nested_svm_map with might_sleep()
Date: Thu, 18 Feb 2010 12:38:30 +0100	[thread overview]
Message-ID: <1266493115-28386-6-git-send-email-joerg.roedel@amd.com> (raw)
In-Reply-To: <1266493115-28386-1-git-send-email-joerg.roedel@amd.com>

The nested_svm_map() function can sleep and must not be
called from atomic context. So annotate that function.
