Christoph Hellwig 6a559523ee nvme: use kref_get_unless_zero in nvme_find_get_ns ... [ Upstream commit 2dd4122854 ] For kref_get_unless_zero to protect against lookup vs free races we need to use it in all places where we aren't guaranteed to already hold a reference. There is no such guarantee in nvme_find_get_ns, so switch to kref_get_unless_zero in this function.
