Some of the error paths inside do_map_benchmark() do not behave well. There is also an insufficient node id validation and an out-of-bounds access in NUMA_NO_NODE case.
Adjust these issues with the following patches.
Changelog v2: * Rework kthread-related error handling patch (thanks to Robin Murphy) and merge patches 1/2 and 2/2 from v1 into a single patch - 1/4 in v2. * Three additional patches: * * Avoid needless copy_to_user if benchmark fails (suggested by Barry Song). * * Fix node id validation (found while testing the previous ones). * * Handle NUMA_NO_NODE correctly. v1: * https://lore.kernel.org/linux-iommu/20240502161827.403338-1-pchelkin@ispras.ru/
