Subject: [PATCH 06/20] inotify: do not use objectid when comparing events
Date: Fri, 12 Jun 2020 12:33:29 +0300	[thread overview]
Message-ID: <20200612093343.5669-7-amir73il@gmail.com> (raw)
In-Reply-To: <20200612093343.5669-1-amir73il@gmail.com>

inotify's event->wd is the object identifier.
Compare that instead of the common fsnotidy event objectid, so
we can get rid of the objectid field later.
