From 1bc6b705eed02dab9feb0e663219b5623f3d684d Mon Sep 17 00:00:00 2001 From: Jeff Cody Date: Tue, 20 Nov 2012 10:21:10 -0500 Subject: block: add bdrv_reopen() support for raw hdev, floppy, and cdrom For hdev, floppy, and cdrom, the reopen() handlers are the same as for the file reopen handler. For floppy and cdrom types, however, we keep O_NONBLOCK, as in the _open function.
