Hi,
Thanks all for giving guides and comments on previous series, this is
the remaining part of the iommufd support.
Besides suggested changes in v6, I'd like to highlight two changes
for final review:
1. Instantiate can_be_deleted callback to fix race where iommufd object
can be deleted before vfio device
2. After careful re-thinking, I'd like to follow Nicolin's suggestion in v5,
remove is_ioas check which indeed looks heavy just for tracepoint.
In fact we can get corresponding info by looking over trace context.
PATCH 1: Introduce iommufd object
PATCH 2-9: add IOMMUFD container and cdev support
PATCH 10-17: fd passing for cdev and linking to IOMMUFD
PATCH 18: make VFIOContainerBase parameter const
PATCH 19-21: Compile out for IOMMUFD for arm, s390x and x86
PATCH 22-26: vfio device init code cleanup
PATCH 27: add iommufd doc
