Subject: [PATCH 06/19] fanotify: reserve event bit of deprecated FAN_DIR_MODIFY
Date: Thu, 21 Nov 2024 12:22:05 +0100 [thread overview]
Message-ID: <20241121112218.8249-7-jack@suse.cz> (raw)
In-Reply-To: <20241121112218.8249-1-jack@suse.cz>
From: Amir Goldstein <amir73il@gmail.com>
Avoid reusing it, because we would like to reserve it for future
FAN_PATH_MODIFY pre-content event.
