[libvirt] [PATCH 0/7] Restore code to allow unpriv_sgio for hostdev SCSI generic

[John Ferlan]

https://bugzilla.redhat.com/show_bug.cgi?id=1072736

This series of patches unreverts the functionality from commit id 'ce346623'
which reverted the original functionality.

Since pure revert caused too many conflicts and because the code has
undergone a few changes since the prior reversion, I had to restore
the code by rote method.  The reversion includes some refactorings to
make the final check much easier to handle.  Of note patch 3 covers much
of what was adjusted in the reverted patch 'qemuCheckSharedDevice'.
Patch 4 expands the driver lock to cover the same space as the
similar disk code - I can take the other as well and shorten the
time the disk code has the lock. Keeping them similar is mostly a
sanity thing.


John Ferlan (7):
  qemu: Introduce qemuIsSharedHostdev
  qemu: Introduce qemuGetHostdevPath
  qemu: Refactor qemuCheckSharedDisk to create virCheckUnprivSGIO
  qemu: Refactor qemuAddSharedHostdev and qemuRemoveSharedHostdev
  qemu: Extract qemuGetHostdevPath from qemuGetSharedHostdevKey
  qemu: Add ability to set sgio values for hostdev
  qemu: Add check for unpriv sgio for SCSI generic host device
