Right now buffer cloning is an all-or-nothing kind of thing - either the whole table is cloned from a source to a destination ring, or nothing at all. However, it's not always desired to clone the whole thing. Allow for the application to specify a source and destination offset, and a number of buffers to clone. If the destination offset is non-zero, then allocate sparse nodes upfront. Signed-off-by: Jens Axboe <axboe@kernel.dk> |
