-This is the end of the second part of the [synchronization primitives](https://en.wikipedia.org/wiki/Synchronization_%28computer_science%29) chapter in the Linux kernel. In the previous [part](https://0xax.gitbooks.io/linux-insides/content/SyncPrim/sync-1.html) we already meth the first synchronization primitive `spinlock` provided by the Linux kernel which is implemented as `ticket spinlock`. In this part we saw another implementation of the `spinlock` mechanism - `queued spinlock`. In the next part we will continue to dive into synchronization primitives in the Linux kernel.
