Subject: [PATCH v3 14/16] ipsec: use previous value atomic fetch operations
Date: Mon, 20 Mar 2023 12:00:34 -0700 [thread overview]
Message-ID: <1679338836-21321-15-git-send-email-roretzla@linux.microsoft.com> (raw)
In-Reply-To: <1679338836-21321-1-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.
