From 75369089820473eac45e9ddd970081901a373c08 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Wed, 17 Jul 2019 21:22:38 -0400 Subject: SUNRPC: Ensure the bvecs are reset when we re-encode the RPC request The bvec tracks the list of pages, so if the number of pages changes due to a re-encode, we need to reset the bvec as well. Fixes: 277e4ab7d530 ("SUNRPC: Simplify TCP receive code by switching...")
