Thank for the info. I am less familiar with that kind of issues on otherSInce it's the unlock path,. you need to use the "mb__*before*"
architecture. I will add a smp_mb__after_atomic_dec()& send out a new
versions, since presumably you want to protect what is inside the lock

will certainly put the right mb functions depending on whether it is a
lock or unlock function.
