| Subject: UBI: Dispatch update notification if the volume is updated |
| |
| From: Ezequiel Garcia <ezequiel.garcia@free-electrons.com> |
| |
| commit fda322a1b3b9e8ee231913c500f73c6988b1aff5 upstream. |
| |
| The UBI_IOCVOLUP ioctl is used to start an update and also to |
| truncate a volume. In the first case, a "volume updated" notification |
| is dispatched when the update is done. |
| |
| This commit adds the "volume updated" notification to be also sent when |
| the volume is truncated. This is required for UBI block and gluebi to get |
| notified about the new volume size. |
