Subject: [PATCH] redhat: rh_kabi: Fix RH_KABI_SET_SIZE to use dereference
|
|
operator

|
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.
