| D | mutex-design.txt | 23 Mutexes are represented by 'struct mutex', defined in include/linux/mutex.h
24 and implemented in kernel/locking/mutex.c. These locks use an atomic variable
34 When acquiring a mutex, there are three possible paths that can be
46 soon. The mutex spinners are queued up using MCS lock so that only
47 one spinner can compete for the mutex.
58 waiting to spin on mutex owner, only to go directly to slowpath upon
75 The mutex subsystem checks and enforces the following rules:
77 - Only one task can hold the mutex at a time.
78 - Only the owner can unlock the mutex.
81 - A mutex must only be initialized via the API (see below).
