[libvirt] [PATCH v2 00/10] Restore code to allow unpriv_sgio for hostdev SCSI generic

v1 here: http://www.redhat.com/archives/libvir-list/2015-June/msg00814.html Changes since v1: - Add doc patch 1 to indicate that this feature may only be supported by certain kernels - Adjust former patch 1 to add call to qemuIsSharedHostdev from qemuSetUnprivSGIO - Insert patches 7 & 8 which essentially refactor qemuSetUnprivSGIO a bit. There should be no functional difference - Patch 9 is now a much slimmer former patch 6 The end result is that 'generically speaking' if any kernel supports setting the unprivileged SGIO feature, then these patches provide the capability to do so. Although as pointed out in the review of v1 only one specific downstream kernel supports the feature, that doesn't mean other distros couldn't add support in the same manner. So rather than just remove all traces from libvirt completely, it seems it would be reasonable to keep the checks in place and if a kernel then decides to add support this code exists to assist.
