Subject: [PATCH v2 05/14] inotify: Don't force FS_IN_IGNORED
Date: Tue, 15 Jun 2021 19:55:47 -0400	[thread overview]
Message-ID: <20210615235556.970928-6-krisman@collabora.com> (raw)
In-Reply-To: <20210615235556.970928-1-krisman@collabora.com>

According to Amir:

"FS_IN_IGNORED is completely internal to inotify and there is no need
to set it in i_fsnotify_mask at all, so if we remove the bit from the
output of inotify_arg_to_mask() no functionality will change and we will
be able to overload the event bit for FS_ERROR."

This is done in preparation to overload FS_ERROR with the notification
mechanism in fanotify.
