Subject: KVM: SVM: Annotate nested_svm_map with might_sleep()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=6c3bd3d7660c35a703073b81eccfd5a3b7c15295;p=linux-beck.git

KVM: SVM: Annotate nested_svm_map with might_sleep()

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