Is it possible to add pid and comm members to the event structure to increase the display of user and thread information?

[Nixiaoming]

Inotify api cannot display information about users and processes.
That is, you can only know that the file event is generated, but you don't know who triggered the event, which is not conducive to fault location.
Is it possible to add pid and comm members to the event structure to increase the display of user and thread information?

Example:
diff --git a/fs/notify/inotify/inotify.h b/fs/notify/inotify/inotify.h
