 This part opens new chapter in the [linux-insides](http://0xax.gitbooks.io/linux-insides/content/) book. Timers and time management related stuff was described in the previous [chapter](https://0xax.gitbooks.io/linux-insides/content/Timers/index.html). Now time to go next. As you may understand from the part's title, this chapter will describe [synchronization](https://en.wikipedia.org/wiki/Synchronization_%28computer_science%29) primitives in the Linux kernel.
 
-As always, before we will consider something synchronization related, we will try to know what is `synchronization primitive` in general. Actually, synchronization primitive is a software mechanism which provides ability to two or more [parallel](https://en.wikipedia.org/wiki/Parallel_computing) processes or threads to not execute simultaneously one the same segment of a code. For example let's look on the following piece of code:
