From 7ea37c30660d4cd6aca21a324fabefe23b89f931 Mon Sep 17 00:00:00 2001 From: Max Reitz Date: Tue, 13 Jun 2017 22:20:53 +0200 Subject: block: Add PreallocMode to bdrv_truncate() For block drivers that just pass a truncate request to the underlying protocol, we can now pass the preallocation mode instead of aborting if it is not PREALLOC_MODE_OFF.
