From c58c13c897478bd7db62e9122b480214b0e166a4 Mon Sep 17 00:00:00 2001 From: Gabriel Krisman Bertazi Date: Mon, 25 Oct 2021 16:27:37 -0300 Subject: [PATCH] fanotify: Wrap object_fh inline space in a creator macro [ Upstream commit 2c5069433a3adc01ff9c5673567961bb7f138074 ] fanotify_error_event would duplicate this sequence of declarations that already exist elsewhere with a slight different size. Create a helper macro to avoid code duplication.
