This is a note to let you know that I've just added the patch titled eventfs: Remove fsnotify*() functions from lookup() to the 6.7-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: eventfs-remove-fsnotify-functions-from-lookup.patch and it can be found in the queue-6.7 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. >From SRS0=eEWY=JP=rostedt.homelinux.com=rostedt@xxxxxxxxxx Tue Feb 6 12:35:08 2024 From: Steven Rostedt <rostedt@xxxxxxxxxxx> Date: Tue, 06 Feb 2024 06:32:20 -0500 Subject: eventfs: Remove fsnotify*() functions from lookup() To: linux-kernel@xxxxxxxxxxxxxxx, stable@xxxxxxxxxxxxxxx Cc: Linus Torvalds <torvalds@xxxxxxxxxxxxxxxxxxxx>, Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx>, Sasha Levin <sashal@xxxxxxxxxx>, Masami Hiramatsu <mhiramat@xxxxxxxxxx>, Mark Rutland <mark.rutland@xxxxxxx>, Mathieu Desnoyers <mathieu.desnoyers@xxxxxxxxxxxx>, Christian Brauner <brauner@xxxxxxxxxx>, Al Viro <viro@xxxxxxxxxxxxxxxxxx>, Ajay Kaher <ajay.kaher@xxxxxxxxxxxx>, Al Viro <viro@xxxxxxxxxxxxxxxxxx> Message-ID: <20240206113401.654906760@xxxxxxxxxxxxxxxxxxxxx> From: "Steven Rostedt (Google)" <rostedt@xxxxxxxxxxx> commit 12d823b31fadf47c8f36ecada7abac5f903cac33 upstream. The dentries and inodes are created when referenced in the lookup code. There's no reason to call fsnotify_*() functions when they are created by a reference. It doesn't make any sense.
