# Synchronization primitives in the Linux kernel.

This chapter describes synchronization primitivies in the Linux kernel.

* [Introduction to spinlocks](http://0xax.gitbooks.io/linux-insides/content/SyncPrim/sync-1.html) - the first part of this chapter describes implementation of spinlock mechanism in the Linux kernel.
* [Queued spinlocks](https://0xax.gitbooks.io/linux-insides/content/SyncPrim/sync-2.html) - the second part describes another type of spinlocks - queued spinlocks.
* [Semaphores](https://0xax.gitbooks.io/linux-insides/content/SyncPrim/sync-3.html) - this part describes implementation of `semaphore` synchronization primitive in the Linux kernel.
* [Mutual exclusion](https://0xax.gitbooks.io/linux-insides/content/SyncPrim/sync-4.html) - this part describes - `mutex` in the Linux kernel.
