# Synchronization primitives

This chapter describes synchronization primitives in the Linux kernel.

* [Introduction to spinlocks](https://0xax.gitbook.io/linux-insides/summary/syncprim/linux-sync-1) - the first part of this chapter describes implementation of spinlock mechanism in the Linux kernel.
* [Queued spinlocks](https://0xax.gitbook.io/linux-insides/summary/syncprim/linux-sync-2) - the second part describes another type of spinlocks - queued spinlocks.
* [Semaphores](https://0xax.gitbook.io/linux-insides/summary/syncprim/linux-sync-3) - this part describes implementation of `semaphore` synchronization primitive in the Linux kernel.
* [Mutual exclusion](https://0xax.gitbook.io/linux-insides/summary/syncprim/linux-sync-4) - this part describes - `mutex` in the Linux kernel.
* [Reader/Writer semaphores](https://0xax.gitbook.io/linux-insides/summary/syncprim/linux-sync-5) - this part describes special type of semaphores - `reader/writer` semaphores.
* [Sequential locks](https://0xax.gitbook.io/linux-insides/summary/syncprim/linux-sync-6) - this part describes sequential locks in the Linux kernel.
