Add support to discard blocks in a raw image residing on an XFS filesystem by calling the XFS_IOC_UNRESVSP64 ioctl to punch holes. Support for other hole punching mechanisms can be added when they become available. Signed-off-by: NChristoph Hellwig <hch@lst.de> Signed-off-by: NKevin Wolf <kwolf@redhat.com>

discard [-Cq] off len -- discards a number of bytes at a specified offset discards a range of bytes from the given offset Example: 'discard 512 1k' - discards 1 kilobyte from 512 bytes into the file Discards a segment of the currently open file. -C, -- report statistics in a machine parsable format -q, -- quite mode, do not show I/O statistics Signed-off-by: NStefan Hajnoczi <stefanha@linux.vnet.ibm.com> Signed-off-by: NKevin Wolf <kwolf@redhat.com>

Support discards via the WRITE SAME command with the unmap bit set, and tell the initiator about the support for it via the block limit and the new thin provisioning EVPD pages.

Add a new bdrv_discard method to free blocks in a mapping image, and a new drive property to set the granularity for these discard. If no discard granularity support is set discard support is disabled. Signed-off-by: NChristoph Hellwig <hch@lst.de> Signed-off-by: NKevin Wolf <kwolf@redhat.com>

We register the vm change state handler in a PCI BAR map() function. This function can be called multiple times throughout the lifetime of a PCI IDE device. This results in duplicate vm change state handlers being register, none of which are ever unregistered. Instead, register the vm change state handler in the device's init function once and for all. piix tested, cmd646 and via not tested.

This patch re-factors img_create() moving the code doing the actual work into block.c where it can be shared with QEMU.

We hook into transfer_start and immediately call the end function for ahci. This means that everything needs to be in place for the end function when we start the transfer, so let's move the function down to where all state is in place.

This introduces strtosz_suffix() which allows the caller to specify a default suffix in case the non default of MB is wanted. strtosz() is kept as a wrapper for strtosz_suffix() which keeps it's current default of MB.

Backing filenames may contain a protocol. The code currently doesn't consider this case and produces filenames that embed "<protocol>:". Don't combine filenames if the backing filename contains a protocol. Based on an earlier patch by Anthony Liguori <aliguori@us.ibm.com>.

The bdrv_find_protocol() function returns NULL if an unknown protocol name is given. It returns the "file" protocol when the filename contains no protocol at all. This makes it difficult to distinguish between paths which contain a protocol and those which do not. Factor out a helper function that tests whether or not a filename has a protocol. The next patch makes use of this function. Signed-off-by: NStefan Hajnoczi <stefanha@linux.vnet.ibm.com> Signed-off-by: NKevin Wolf <kwolf@redhat.com>

If a user decides to punish a guest by revoking its block device via drive_del, and subsequently also attempts to remove the pci device backing it, and the device is using blockdev_auto_del() then we get a segfault when we attempt to access dinfo->auto_del.[1] The fix is to check if drive_get_by_blockdev() actually returns a valid dinfo pointer or not. 1.
