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.
