Subject: [PATCH v3 04/17] iommu: Export iommu_get_resv_regions()
Date: Tue, 21 Mar 2023 16:14:38 -0300 [thread overview]
Message-ID: <4-v3-61d41fd9e13e+1f5-iommufd_alloc_jgg@nvidia.com> (raw)
In-Reply-To: <0-v3-61d41fd9e13e+1f5-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.
