Subject: [PATCH 24/26] treewide: Rename dma_buf_dynamic_attach() to dma_buf_sgt_dynamic_attach()
Date: Mon, 26 Oct 2026 16:36:15 +1100 [thread overview]
Message-ID: <20261026053623.202642-25-apopple@nvidia.com> (raw)
In-Reply-To: <20261026053623.202642-1-apopple@nvidia.com>
From: Jason Gunthorpe <jgg@nvidia.com>
This attach function always creates a SGT mapping type importer.
