Subject: [PATCH v4 00/10] Rework REFCOUNT_FULL using atomic_fetch_* operations
Date: Wed, 30 Oct 2019 14:30:25 +0000 [thread overview]
Message-ID: <20191030143035.19440-1-will@kernel.org> (raw)
Hi all,
This is version four of the patches I previously posted here:
v1: https://lkml.kernel.org/r/20190802101000.12958-1-will@kernel.org
v2: https://lkml.kernel.org/r/20190827163204.29903-1-will@kernel.org
v3: https://lkml.kernel.org/r/20191007154703.5574-1-will@kernel.org
Changes since v3 include:
- Add description of racy behaviour include/linux/refcount.h
- Fix saturation behaviour in refcount_sub_and_test()
- Added Acks and Tested-bys
Cheers,
Will
