Piccoli" <gpiccoli@...lia.com>, Nick Terrell <terrelln@...com>, linux-kernel@...r.kernel.org, linux-hardening@...r.kernel.org Subject: [PATCH 0/5] pstore: Use zstd directly by default for compression Hi, Okay, here is a very lightly tested version of using zstd directly, which should save 128KB per CPU compare to using crypto API. This leaves the crypto API available, though, if someone wants to use it instead. Even supporting both, this is a net reduction in code, due to dropping all the zbufsize logic. How does this look? -Kees Kees Cook (5): pstore: Remove worse-case compression size logic pstore: Allow for arbitrary compression algorithm pstore: Use size_t for compress/decompression type widths pstore: Refactor compression initialization pstore: Use zstd directly by default for compression fs/pstore/Kconfig | 131 +++++----------- fs/pstore/platform.c | 358 ++++++++++++++++++++----------------------- 2 files changed, 209 insertions(+), 280 deletions(-) -- 2.34.1
