From 8bfea15ddac3a0ae832f181653c36e020f24f007 Mon Sep 17 00:00:00 2001 From: Kevin Wolf Date: Fri, 11 Apr 2014 19:16:36 +0200 Subject: block: Unlink temporary files in raw-posix/win32 Instead of having unlink() calls in the generic block layer, where we aren't even guarateed to have a file name, move them to those block drivers that are actually used and that always have a filename. Gets us rid of some #ifdefs as well. The patch also converts bs->is_temporary to a new BDRV_O_TEMPORARY open flag so that it is inherited in the protocol layer and the raw-posix and raw-win32 drivers can unlink the file.
