Subject: [PATCH v3 1/8] fanotify: fix collision of internal and uapi mark flags
Date: Thu,  4 Oct 2018 00:25:32 +0300	[thread overview]
Message-ID: <20181003212539.2384-2-amir73il@gmail.com> (raw)
In-Reply-To: <20181003212539.2384-1-amir73il@gmail.com>

The new mark flag FAN_MARK_FILESYSTEMS collides with existing internal
flag FAN_MARK_ONDIR. Change internal flag value to avoid the collision.

Fixes: d54f4fba889b ("fanotify: add API to attach/detach super block mark")
