This commit delays the point at which bdrv_new (and hence blk_open on the underlying device) is called from blk_init to blk_connect. This ensures that in an inbound live migrate, the block device is not opened until it has been closed at the other end. This is in preparation for supporting devices with open/close consistency without using O_DIRECT. This commit does NOT itself change O_DIRECT

From: Stefano Stabellini <stefano.stabellini@eu.citrix.com> When disk is a cdrom and the drive is empty the "params" node in xenstore might be missing completely: cope with it instead of segfaulting. Updated in v2: - actually removed the strchr(blkdev->params, '':'') that caused the segfault; - free all the allocated strings from xenstore before returning;

This patch-set deals with some of the style isues in blkvsc_drv.c. We also get rid most of the "dead code" in this file: 1) Get rid of most of the forward declarations in this file. The only remaining forward declarations are to deal with circular dependencies. 2) Get rid of most of the dead code in the file. Some of the functions in this file are place holders - they

The latest upstream merge changed struct block_device_operations: This merge got rid of blkvsc_media_changed and introduced the function blkvsc_check_events. This broke all the patches that were sent after the tree was closed the last time. This is a resend of this patch-set to account for this change in the kernel. More cleanup.

More cleanup. In this patch-set we deal with the following issues: 1) While a Linux guest on Hyper-V can be assigned removable media devices (DVD, floppy etc), these devices are not handled by the Hyper-V block driver. So, we cleanup all the dead code dealing with removable media devices. 2) There were multiple functions to retrieve information about the device. Since much of
