[PATCH 10/16] userfaultfd: Replace spin_is_locked() with lockdep

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



lockdep_assert_held() is better suited to checking locking requirements,
since it won't get confused when someone else holds the lock. This is
also a step towards possibly removing spin_is_locked().
