From fda322a1b3b9e8ee231913c500f73c6988b1aff5 Mon Sep 17 00:00:00 2001 From: Ezequiel Garcia Date: Fri, 29 Aug 2014 18:42:30 -0300 Subject: UBI: Dispatch update notification if the volume is updated 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.
