This commit adds a __data_racy type qualifier that enables kernel developers to inform KCSAN that a given variable is a shared variable without needing to mark each and every access. This allows pre-KCSAN code to be correctly (if approximately) instrumented withh very little effort, and also provides people reading the code a clear indication that the variable is in fact shared. In addition, it permits incremental transition to per-access KCSAN marking, so that (for example) a given subsystem can be transitioned one variable at a time, while avoiding large numbers of KCSAN warnings during this transition. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEbK7UrM+RBIrCoViJnr8S83LZ+4wFAmY+i+cTHHBhdWxtY2tA a2VybmVsLm9yZwAKCRCevxLzctn7jJQ1D/9eOBNKefU7duZgAOzUizPdxRvxKzPx UENz6DU/xXB+jcaWiRvdWyFgIFnUS/TaZcwtthXh4bV1I754dRFy8X9+/uHd8AVY MUwRkhY3Nie/MgkvLrEmMsfWn9zSUp0Pwq4dwFdhvb0aosFSn7PgtSrE62+RafpZ k1abEUa62MfSLJjJ7C8ThYk9broAgz37drloAStAr4PvrCM4JaoeChkStaAK80z1 qq3EblLtXlzKcW1UNkvsbTxcnv+quLsI4EHKSnN3O8l47/F/k52ENz5Qp1pYTOLk kO3IZjqFqnIH6Re5eHPA05cwQssJFvsB8gfB+g+kc2uOK/z7wwg0/gqf9SZyaosw ABoaxflfNE/mTzKVgob3wqGyhlsAE/R2k02yoMad4X78ATOi9RpjdH6xC4OOXYfV 4P8g2hGAHNR8UgYosXFx+YCu2ktGYyfsqTicMaaaECUfxFeJjJ1QqgwHYHADDDv/ x8UxggAco1jul+6fikPGnjDgBN5IJOwS26NEUguqAFqYMTF8OO/x6ag6cqG5nk3a b41GF4HEfoQtJduuOv8jVntyTRU7zbpH+AVuinQ1V34kpYp5fE75p30P4UUjMegA JaAoOeD9aebEUHHlujomaV/QKSHobYLmYp/ARe2QZjp7aiELcjvV/ThOdwRxGEZg Zl4qRaGc9YO/Ag== =f1gr -----END PGP SIGNATURE----- Merge tag 'kcsan.2024.05.10a' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu Pull kcsan update from Paul McKenney: "Introduce __data_racy type qualifier This adds a __data_racy type qualifier that enables kernel developers to inform KCSAN that a given variable is a shared variable without needing to mark each and every access.
