Subject: [PATCH v7 04/19] iommu: Export iommu_get_resv_regions()
Date: Mon, 15 May 2023 11:00:19 -0300 [thread overview]
Message-ID: <4-v7-6c0fd698eda2+5e3-iommufd_alloc_jgg@nvidia.com> (raw)
In-Reply-To: <0-v7-6c0fd698eda2+5e3-iommufd_alloc_jgg@nvidia.com>
iommufd wants to use this in the next patch. For some reason the
iommu_put_resv_regions() was already exported.
