Subject: [PATCHSET v2 0/2] Add support for cloning partial buffer sets
Date: Wed, 30 Oct 2024 19:44:54 -0600 [thread overview]
Message-ID: <20241031014629.206573-1-axboe@kernel.dk> (raw)
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
