Hi, 6.12 added buffer cloning support, but it's an all-or-nothing kind of thing - if there's an existing buffer table in the destination ring, then nothing can be cloned to it. This adds support for cloning partial buffer sets, specifying a source/dest offset and the number of buffers to clone. And it allows cloning to replace existing nodes as well, specified with a separate flag. Changes since v1: - Rebase on current tree (no rsrc_empty_node) - Rewrite the replacement code to be much simpler - Write more test cases -- Jens Axboe
