This is the fourth part of the [chapter](https://0xax.gitbooks.io/linux-insides/content/SyncPrim/index.html) which describes synchronization primitives in the Linux kernel and in the previous parts we finished to consider different types [spinlocks](https://en.wikipedia.org/wiki/Spinlock), [semaphore](https://en.wikipedia.org/wiki/Semaphore_%28programming%29) and [mutex](https://en.wikipedia.org/wiki/Mutual_exclusion) synchronization primitives. In We will continue to learn [synchronization primitives](https://en.wikipedia.org/wiki/Synchronization_%28computer_science%29) in this part and start to consider special type of synchronization primitives - [readers–writer lock](https://en.wikipedia.org/wiki/Readers%E2%80%93writer_lock).

The first synchronization primitive of this type will be already familar for us - [semaphore](https://en.wikipedia.org/wiki/Semaphore_%28programming%29). As in all previous parts of this [book](https://0xax.gitbooks.io/linux-insides/content), before we will consider implementation of the `reader/writer semaphores` in the Linux kernel, we will start from the theoretical side and will try to understand what is the difference between `reader/writer semaphores` and `normal semaphores`.
