NAME

6       mutex_trylock - try to acquire the mutex, without waiting
7

SYNOPSIS

9       int __sched mutex_trylock(struct mutex * lock);
10

ARGUMENTS

12       lock
13           the mutex to be acquired
14

DESCRIPTION

16       Try to acquire the mutex atomically. Returns 1 if the mutex has been
17       acquired successfully, and 0 on contention.
18

NOTE

20       this function follows the spin_trylock convention, so it is negated
21       from the down_trylock return values! Be careful about this when
22       converting semaphore users to mutexes.
23
24       This function must not be used in interrupt context. The mutex must be
25       released by the same task that acquired it.
