 So, what is it `seqlock` synchronization primitive and how it works? Let's try to answer on these questions in this paragraph. Actually `sequential locks` were introduced in the Linux kernel 2.6.x. Main point of this synchronization primitive is to provide fast and lock-free access to shared resource. Since the heart of `sequential lock` synchronization primitive is [spinlock](https://0xax.gitbooks.io/linux-insides/content/SyncPrim/sync-1.html) synchronization primitive, `sequential locks` work in situations where the protected resources are small and simple. Additionally write access must be rare and also should be fast. 
 
-Work of this synchronization primitive is based on the sequence of events counter. Actually a `sequential lock` allows to free access to a resource for readers, but each reader must check existence of conflicts with a writer. This synchronization primitive introduces special counter. The main algorithm of work of `sequential locks` is simple: Each writer which acquired a sequential lock increments this counter and additionaly acquires a [spinlock](https://0xax.gitbooks.io/linux-insides/content/SyncPrim/sync-1.html). When this writer will finish, it will release acquired spinlock to give access to other writers and increment the counter of a sequential lock again.

 Read only access works on the following principle gets value of a `sequential lock` counter before it will enter into [critical section](https://en.wikipedia.org/wiki/Critical_section) and compares it with the value of the same `sequential lock` counter at the exit of critical section. If their values are equal, this means that there weren't writers for this period. If their values are not equal, this means that a writer has incremented the counter during the [critical section](https://en.wikipedia.org/wiki/Critical_section). This conflict means that reading of protected data must be repeated.
