Message-ID: <1555847596-1754-1-git-send-email-galpress@amazon.com> Date: Sun, 21 Apr 2019 14:53:16 +0300 From: Gal Pressman <galpress@...zon.com> To: <linux-kernel@...r.kernel.org> CC: Mukesh Ojha <mojha@...eaurora.org>, Gal Pressman <galpress@...zon.com>, Jason Gunthorpe <jgg@...lanox.com> Subject: [PATCH v2] lib/scatterlist: Remove leftover from sg_page_iter comment Commit d901b2760dc6 ("lib/scatterlist: Provide a DMA page iterator") added the sg DMA iterator but a leftover remained in the sg_page_iter documentation as you cannot get the page dma address (only the page itself), fix it.
