Whatever for; it'd be the exact identical same functions as for atomic_t, except for a giant amount of code duplication to deal with the new type. That is; today we merged a bunch of scripts that generates most of atomic*_t, so we could probably script uatomic*_t wrappers with minimal effort, but it would add several thousand lines of code to each compile for absolutely no reason what so ever. > This reminds me of this sooooo silly patch :/ > > https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=adb03115f4590baa280ddc440a8eff08a6be0cb7 Yes, that's stupid. UBSAN is just wrong there.
