Date: Mon, 25 Oct 2021 16:27:37 -0300 From: Gabriel Krisman Bertazi <krisman@...labora.com> To: amir73il@...il.com, jack@...e.com Cc: djwong@...nel.org, tytso@....edu, david@...morbit.com, dhowells@...hat.com, khazhy@...gle.com, linux-fsdevel@...r.kernel.org, linux-api@...r.kernel.org, linux-ext4@...r.kernel.org, Gabriel Krisman Bertazi <krisman@...labora.com>, kernel@...labora.com, Jan Kara <jack@...e.cz> Subject: [PATCH v9 22/31] fanotify: Wrap object_fh inline space in a creator macro 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.
