| D | mutex-design.rst | 26 Mutexes are represented by 'struct mutex', defined in include/linux/mutex.h
27 and implemented in kernel/locking/mutex.c. These locks use an atomic variable
37 When acquiring a mutex, there are three possible paths that can be
49 soon. The mutex spinners are queued up using MCS lock so that only
50 one spinner can compete for the mutex.
61 waiting to spin on mutex owner, only to go directly to slowpath upon
78 The mutex subsystem checks and enforces the following rules:
80 - Only one task can hold the mutex at a time.
81 - Only the owner can unlock the mutex.
84 - A mutex must only be initialized via the API (see below).
