From 4f5f3b6028343d687d0533329b130e4b8280ab32 Mon Sep 17 00:00:00 2001 From: Anna Schumaker Date: Thu, 21 Jul 2022 14:21:31 -0400 Subject: SUNRPC: Introduce xdr_stream_move_subsegment() I do this by creating an xdr subsegment for the range we will be operating over. This lets me shift data to the correct place without potentially overwriting anything already there.
