Subject: [PATCH] redhat: rh_kabi: Fix RH_KABI_SET_SIZE to use dereference
operator
RH-Acked-by: Prarit Bhargava <prarit@redhat.com>
RH-Acked-by: Jiri Benc <jbenc@redhat.com>
Upstream Status: RHEL only
Since this macro is intended to record the sizeof extension structs that
are dynamically allocated, using the structure dereference operator '->'
is a better choice, else the macro would have to be invoked with the
_name argument dereferenced as (*_name).
Also added a short note explaining that, unlike the other RH_KABI
macros that are invoked from within structs, this macro is invoked
outside a struct and therefore needs a semicolon termination.
