2010-12-02virtio-9p: fix build on !CONFIG_UTIMENSATHidetoshi Seto
This patch introduce a fallback mechanism for old systems that do not support utimensat(). This fix build failure with following warnings: hw/virtio-9p-local.c: In function 'local_utimensat': hw/virtio-9p-local.c:479: warning: implicit declaration of function 'utimensat' hw/virtio-9p-local.c:479: warning: nested extern declaration of 'utimensat' and: hw/virtio-9p.c: In function 'v9fs_setattr_post_chmod': hw/virtio-9p.c:1410: error: 'UTIME_NOW' undeclared (first use in this function) hw/virtio-9p.c:1410: error: (Each undeclared identifier is reported only once hw/virtio-9p.c:1410: error: for each function it appears in.) hw/virtio-9p.c:1413: error: 'UTIME_OMIT' undeclared (first use in this function) hw/virtio-9p.c: In function 'v9fs_wstat_post_chmod': hw/virtio-9p.c:2905: error: 'UTIME_OMIT' undeclared (first use in this function) [NOTE: At this time virtio-9p is only user of utimensat(), and is available only when host is linux and CONFIG_VIRTFS is defined. So there are no similar warning for win32.

2010-12-02[virtio-9p] Add datasync to server side TFSYNC/RFSYNC for dotlVenkateswararao Jujjuri (JV)
SYNOPSIS size[4] Tfsync tag[2] fid[4] datasync[4] size[4] Rfsync tag[2] DESCRIPTION The Tfsync transaction transfers ("flushes") all modified in-core data of file identified by fid to the disk device (or other permanent storage device) where that file resides. If datasync flag is specified data will be fleshed but does not flush modified metadata unless that metadata is needed in order to allow a subsequent data retrieval to be correctly handled.

2010-11-29ide: Reset current_addr after stopping DMAKevin Wolf
Whenever SSBM is reset in the command register all state information is lost. Restarting DMA means that current_addr must be reset to the base address of the PRD table. The OS is not required to change the base address register before starting a DMA operation, it can reuse the value it wrote for an earlier request.

2010-11-25scsi: Return SAM status codesHannes Reinecke
Traditionally, the linux stack is using SCSI status codes which are shifted by one as compared to those defined in SAM. A SCSI emulation should naturally return the SAM defined codes, not the linux ones. So to avoid any confusion this patch modifies the existing definitions to match those found in SAM and removes any (now obsolete) byte-shift from the returned status codes.

2010-11-25scsi: Increase the number of possible devicesHannes Reinecke
The SCSI parallel interface has a limit of 8 devices, but not the SCSI stack in general. So we should be removing the hard-coded limit and use MAX_SCSI_DEVS instead. And we only need to scan those devices which are allocated by the bus.

2010-11-24Implement drive_del to decouple block removal from device removalRyan Harper
Currently device hotplug removal code is tied to device removal via ACPI. All pci devices that are removable via device_del() require the guest to respond to the request. In some cases the guest may not respond leaving the device still accessible to the guest. The management layer doesn't currently have a reliable way to revoke access to host resource in the presence of an uncooperative guest. This patch implements a new monitor command, drive_del, which provides an explicit command to revoke access to a host block device. drive_del first quiesces the block device (qemu_aio_flush; bdrv_flush() and bdrv_close()). This prevents further IO from being submitted against the host device. Finally, drive_del cleans up pointers between the drive object (host resource) and the device object (guest resource).

2010-11-24scsi-disk: Move active request assertsStefan Hajnoczi
SCSI read/write requests should not be re-issued before the current fragment of I/O completes. There are asserts in scsi-disk.c that guard this constraint but they trigger on SPARC Linux 2.4. It turns out that the asserts are too early in the code path and don't allow for read requests to terminate. Only the read assert needs to be moved but move the write assert too for consistency.
