# HEAD: ea6ee1bac6034cb4e91bcc229ed1354ca1a024d5: tools/memory-model: Code reorganization in lock.cat (2024-06-06 11:24:58 -0700)
----------------------------------------------------------------
lkmm: Fix corner-case locking bug and improve documentation
A simple but odd single-process litmus test acquires and immediately
releases a lock, then calls spin_is_locked(). LKMM acts if it was
a deadlock due to an assumption that spin_is_locked() will follow a
spin_lock() or some other process's spin_unlock(). This litmus test
manages to violate this assumption because the spin_is_locked() follows
the same process's spin_unlock().
This series fixes this bug, reorganizes and optimizes the lock.cat model,
and updates documentation.
