Message-ID: <20200506132816.GJ8043@willie-the-truck> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline User-Agent: Mutt/1.10.1 (2018-07-13) Sender: linux-kernel-owner@vger.kernel.org Precedence: bulk List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Hi TIP folks, I'm looking to rebase my READ_ONCE() series [1] on top of the KCSAN patches so that we can get them in for 5.8. However, tip/locking/kcsan seems to be missing some bits: * An update to checkpatch.pl to warn about missing comments for data_race(): https://lore.kernel.org/r/20200401101714.44781-1-elver@google.com * I'm unable to apply these two patches from Marco that are needed for my READ_ONCE() work: https://lore.kernel.org/lkml/20200424154730.190041-1-elver@google.com/ I think these depend on stuff that has been queued by Paul, and appears in linux-next, but to be honest with you I'm quite confused about what is queued for 5.8 and what isn't. What's the best base for me to use? Cheers, Will [1] https://lore.kernel.org/r/20200421151537.19241-1-will@kernel.org
