Merge branch 'Dynptr refactorings'
Kumar Kartikeya Dwivedi says: ==================== This is part 1 of https://lore.kernel.org/bpf/20221018135920.726360-1-memxor@gmail.com. This thread also gives some background on why the refactor is being done: https://lore.kernel.org/bpf/CAEf4Bzb4beTHgVo+G+jehSj8oCeAjRbRcm6MRe=Gr+cajRBwEw@mail.gmail.com As requested in patch 6 by Alexei, it only includes patches which refactors the code, on top of which further fixes will be made in part 2. The refactor itself fixes another issue as a side effect. No functional change is intended (except a few modified log messages). Changelog: ---------- v1 -> v2 v1: https://lore.kernel.org/bpf/20221115000130.1967465-1-memxor@gmail.com * Address feedback from Joanne and David, add acks Fixes v1 -> v1 Fixes v1: https://lore.kernel.org/bpf/20221018135920.726360-1-memxor@gmail.com * Collect acks from Joanne and David * Fix misc nits pointed out by Joanne, David * Split move of reg->off alignment check for dynptr into separate change (Alexei) ==================== Signed-off-by: Alexei Starovoitov <ast@kernel.org>
