From f3441d4125fc98995858550a5521b8d7daf0504a Mon Sep 17 00:00:00 2001 From: David Howells Date: Thu, 20 Oct 2022 21:58:36 +0100 Subject: rxrpc: Copy client call parameters into rxrpc_call earlier Copy client call parameters into rxrpc_call earlier so that that can be used to convey them to the connection code - which can then be offloaded to the I/O thread.
