Subject: [PATCH 02/20] svcrdma: Const-ify the xdr_buf arguments
Date: Mon, 26 Oct 2020 14:54:03 -0400 [thread overview]
Message-ID: <160373844359.1886.5240330169912563769.stgit@klimt.1015granger.net> (raw)
In-Reply-To: <160373843299.1886.12604782813896379719.stgit@klimt.1015granger.net>
Clean up: Ensure the code in rw.c does not modify the argument, and
enable callers to also use "const struct xdr_buf *".
