| Subject: [PATCH] BACKPORT: fanotify: add support for create/attrib/move/delete |
| events |
| |
| Add support for events with data type FSNOTIFY_EVENT_INODE |
| (e.g. create/attrib/move/delete) for inode and filesystem mark types. |
| |
| The "inode" events do not carry enough information (i.e. path) to |
| report event->fd, so we do not allow setting a mask for those events |
| unless group supports reporting fid. |
| |
| The "inode" events are not supported on a mount mark, because they do |
| not carry enough information (i.e. path) to be filtered by mount point. |
| |
| The "dirent" events (create/move/delete) report the fid of the parent |
| directory where events took place without specifying the filename of the |
| child. In the future, fanotify may get support for reporting filename |
| information for those events. |
