Subject: vfio/iommu_type1: make use of info.flags
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=d4f50ee2f5b45fc4d9e4142a52edf8b7935a9275;p=linux-beck.git

vfio/iommu_type1: make use of info.flags

The flags entry is there to tell the user that some
optional information is available.

Since we report the iova_pgsizes signal it to the user
by setting the flags to VFIO_IOMMU_INFO_PGSIZES.
