...ODP (On Demand Paging). And a way also exists which is based on non-ODP. From the following links, this way is implemented on efa, irdma and mlx5. 1. iRDMA https://lore.kernel.org/all/20230217011425.498847-1-yanjun.zhu at intel.com/ 2. efa https://lore.kernel.org/lkml/20211007114018.GD2688930 at ziepe.ca/t/ 3. mlx5 https://lore.kernel.org/all/1608067636-98073-5-git-send-email-jianxin.xiong at intel.com/ Because these 2 methods are both implemented on mlx5, have you compared the test results with the 2 methods on mlx5? The most important results should be latency and bandwidth. Please let us...

From: John Hubbard <jhubbard at nvidia.com> Hi, This is mostly Jerome's work, converting the block/bio and related areas to call put_user_page*() instead of put_page(). Because I've changed Jerome's patches, in some cases significantly, I'd like to get his feedback before we actually leave him listed as the author (he might want to disown some or all of these).

Instead of returning -EAGAIN unconditionally, we'd better do that only we're sure the range is overlapped with the metadata area.
