From fc4c128e15b50c73466dcd7234dde02f6fd9e4f8 Mon Sep 17 00:00:00 2001 From: Ilya Dryomov Date: Mon, 16 Nov 2020 17:27:50 +0100 Subject: libceph: change ceph_con_in_msg_alloc() to take hdr ceph_con_in_msg_alloc() is protocol independent, but con->in_hdr (and struct ceph_msg_header in general) is msgr1 specific. While the struct is deeply ingrained inside and outside the messenger, con->in_hdr field can be separated.
