Subject: [PATCH 01/20] SUNRPC: Adjust synopsis of xdr_buf_subsegment()
Date: Mon, 26 Oct 2020 14:53:58 -0400 [thread overview]
Message-ID: <160373843825.1886.3133196140333045174.stgit@klimt.1015granger.net> (raw)
In-Reply-To: <160373843299.1886.12604782813896379719.stgit@klimt.1015granger.net>
Clean up: This enables xdr_buf_subsegment()'s callers to pass in a
const pointer to that buffer.
Signed-off-by: Chuck Lever <chuck.lever@oracle.com>
