Subject: [PATCH 04/11] ARC: atomic64: LLSC: elide unused atomic_{and,or,xor,andnot}_return
Date: Wed, 4 Aug 2021 12:15:47 -0700 [thread overview]
Message-ID: <20210804191554.1252776-5-vgupta@synopsys.com> (raw)
In-Reply-To: <20210804191554.1252776-1-vgupta@synopsys.com>
This is a non-functional change since those wrappers are not
used in kernel sources at all.
Link: http://lists.infradead.org/pipermail/linux-snps-arc/2018-August/004246.html
Suggested-by: Peter Zijlstra (Intel) <peterz@infradead.org>
