Subject: [PATCH v6 06/21] inotify: Don't force FS_IN_IGNORED
Date: Thu, 12 Aug 2021 17:39:55 -0400 [thread overview]
Message-ID: <20210812214010.3197279-7-krisman@collabora.com> (raw)
In-Reply-To: <20210812214010.3197279-1-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.
