HEAD: 2ba5b4130e3d5d05c95981e1d2e660d57e613fda: Documentation/litmus-tests: Make cmpxchg() tests safe for klitmus (2024-05-06 14:29:21 -0700)
----------------------------------------------------------------
lkmm: Upgrade LKMM documentation
This commit upgrades LKMM documentation, perhaps most notably adding
a number of litmus tests illustrating cmpxchg() ordering properties.
TL;DR: Failing cmpxchg() operations provide no ordering.
----------------------------------------------------------------

Documentation/litmus-tests: Add locking tests to README
Documentation/litmus-tests: Demonstrate unordered failing cmpxchg
Documentation/atomic_t: Emphasize that failed atomic operations give no ordering
