mutex_lock_interruptible — acquire the mutex, interruptible
int __sched mutex_lock_interruptible ( | struct mutex * lock); |
Lock the mutex like mutex_lock, and return 0 if the mutex has
been acquired or sleep until the mutex becomes available. If a
signal arrives while waiting for the lock then this function
returns -EINTR.
This function is similar to (but not equivalent to) down_interruptible.
