H A D | io_pagetable.c | 1baf6c5f Mon Oct 30 09:26:33 CDT 2023 Jason Gunthorpe <jgg@nvidia.com> iommufd: Add iopt_area_alloc()
[ Upstream commit 361d744ddd61de065fbeb042aaed590d32dd92ec ]
We never initialize the two interval tree nodes, and zero fill is not the same as RB_CLEAR_NODE. This can hide issues where we missed adding the area to the trees. Factor out the allocation and clear the two nodes.
Fixes: 51fe6141f0f6 ("iommufd: Data structure to provide IOVA to PFN mapping") Link: https://lore.kernel.org/r/20231030145035.GG691768@ziepe.ca Signed-off-by: Jason Gunthorpe <jgg@nvidia.com> Signed-off-by: Sasha Levin <sashal@kernel.org>
