Subject: [PATCH 10/16] net/octeontx: use previous value atomic fetch operations
Date: Fri, 10 Mar 2023 14:15:24 -0800	[thread overview]
Message-ID: <1678486530-20688-11-git-send-email-roretzla@linux.microsoft.com> (raw)
In-Reply-To: <1678486530-20688-1-git-send-email-roretzla@linux.microsoft.com>

Use __atomic_fetch_{add,and,or,sub,xor} instead of
__atomic_{add,and,or,sub,xor}_fetch adding the necessary code to
allow consumption of the resulting value.
