Oh yes. I said essentially the same to Vincenzo a few hours ago in the KHWASAN thread. I suppose that hard-coding these names wouldn't be too bad. Otherwise, I only see something like: #pragma sparse address_space_name(1, "user") to add to "linux/compiler_types.h". It would be more flexible but is a bit ugly. -- Luc
