Description

Repeating use of init_completion() would be able to create possible race condition.
To avoid it we can reinit completion using INIT_COMPLETION(). Commit 41682e03d4f on torvalds fix this problem.

In some cases (for example, if the critical section is used) double use of init_complition() don't lead to error.
