WebIn the Linux kernel, mutexes refer to a particular locking primitive that enforces serialization on shared memory systems, and not only to the generic term referring to ‘mutual exclusion’ found in academia or similar theoretical text books. Mutexes are sleeping locks which behave similarly to binary semaphores, and were introduced in 2006 ... WebAug 11, 2016 · Mutex: a binary semaphore for mutual exclusion between tasks, to protect a critical section. Internally it works much the same way as a binary semaphore, but it is used in a different way. It is “taken” before the critical section and “given” right after, i.e., in the same task. A mutex typically stores the current “owner” task and ...

"WebJan 3, 2024 · A Binary Semaphore is a semaphore whose integer value range over 0 and 1. It is nothing, but similar to a lock, with two values: 0 and 1. Here 0 means busy, while 1 means free. The idea behind using a binary semaphore is that, it allows only one process at a time to enter the critical section (thus allowing it to access the shared resource). " - Binary semaphore mutex

In particular, it can be used to enforce mutual exclusion for a critical section in user code. In this instance, the semaphore would be created with an initial count of one to indicate that no task is executing the critical section of code.
