Subject: [PATCH v3 20/26] xprtrdma: Don't display r_xprt memory addresses in tracepoints
Date: Mon, 19 Apr 2021 14:03:44 -0400 [thread overview]
Message-ID: <161885542436.38598.3942264388482492390.stgit@manet.1015granger.net> (raw)
In-Reply-To: <161885481568.38598.16682844600209775665.stgit@manet.1015granger.net>
The remote peer's IP address is sufficient, and does not expose
details of the kernel's memory layout.
