Subject: [PATCH v2 0/9] refcount: Improve code-gen
Date: Fri, 10 Dec 2021 17:16:18 +0100 [thread overview]
Message-ID: <20211210161618.645249719@infradead.org> (raw)
Hi,
Now with Linus' favourite refcount scheme on :-)
Changes since RFC:
- more cleanups in scripts/atomic/
- rename atomic_*_ofl() to atomic_*_overflow() (null)
- alternative x86 refcount scheme (Linus)
- fix for refcount_dec_not_one()
- opt __refcount_add_not_zero(.i=1)
Boots x86_64 and builds a kernel.
