Hi,
This pull fixes SYNCRONIZE_CACHE handling in both scsi and usb code.
The SYNCRONIZE_CACHE scsi command is different from all other ones:
It doesn't transfer any data, but still doesn't complete instantly.
Both scsi-disk and usb-storage failed to handle this case correctly,
resulting in all sorts of funky assert failures and segfaults when
the guest writes to a virtual usb stick and flushes stuff.
Patches 1-4 are minor cleanups for usb-storage (slighly improved scsi
request tracking). Also Patch 6 depends on these.
Patch 5 is the actual bugfix for scsi-disk.
Patch 6 is the actual bugfix for usb-storage.
Patches 7+8 are bonus fixes for Coverity-spotted issues which are
sitting in the usb patch queue for a while already.
The following changes since commit bc4268998d154b9b3cc86a7b6bd932cc974591c9:
x86: fix pcmpestrm and pcmpistrm (2011-11-19 13:51:27 +0000)
