Recommended 10 articles about reentry

1. Overview This article first introduces the Lock interface, the class hierarchy of ReentrantLock, and the simple principles of the lock function template class AbstractQueuedSynchronizer. Then it explains the internal principles of ReentrantLock by analyzing the lock method and unlock method of ReentrantLock, and finally makes a summary. This article does not cover condition variables in ReentrantLock. 1.1. Lock interface The Lock interface is an abstraction of tools for controlling concurrency. It is more flexible than using the synchronized keyword and can support condition variables. It is a tool for controlling concurrency. Generally speaking, it controls the exclusivity of a certain shared resource. In other words, only one thread can acquire this lock and occupy resources at the same time. If other threads want to acquire the lock, they must wait for this thread to release the lock. ReentrantLock in Java implementation is such a lock. Another kind of lock, which can allow multiple threads to read resources, but can only allow one thread to write resources, ReadWriteLock is like this

5. In-depth analysis of Linux device driver interrupts (1)(3)

Introduction: 6. Non-reentrancy of interrupt handlers In the previous section we mentioned that sometimes interrupts need to be masked , but why should this interrupt be blocked? This is not because it is technically impossible to achieve parallelization of the same interrupt routine, but because of management considerations
