From: Čestmír Kalina <[email protected]> kabi: fix RH_KABI_SET_SIZE macro
Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2024595 Upstream Status: RHEL only commit ce96bb000b3a603533f885485bd875eb7dfbfff2 Author: Jiri Benc <[email protected]> Author: Ivan Vecera <[email protected]> Date: Wed, 1 Apr 2020 13:04:10 -0400 The current implementation of RH_KABI_SET_SIZE() macro does not allow to pass certain expressions as an argument. E.g. RH_KABI_SET_SIZE(&cq->napi, napi_struct_extended) is expanded to: &cq->napi->napi_struct_extended_size_rh = sizeof(struct ...) and this is not correct and should be: (&cq->napi)->napi_struct_extended_size_rh = sizeof(struct ...) The patch fixes the macro this way.
