on what platform?
A Data Synchronization Barrier (DSB) completes when all
instructions before this instruction complete.
A Data Memory Barrier (DMB) ensures that all explicit memory
accesses before the DMB instruction complete before any explicit
memory accesses after the DMB instruction start.
An Instruction Synchronization Barrier (ISB) flushes the pipeline
in the processor, so that all instructions following the ISB are
fetched from cache or memory, after the ISB has been completed.
in any case, i just changed implementation, but did not added any
low-level things , which was not already there.
