简介 众所周知，在fork时，属于进程private的内存页将会进行COW机制。所谓COW，就是一个资源如果需要值拷贝，在读时不创建出副本，仅当写时再创建。...设置父子进程的所有内存页的标志为write protected， 而在mmap中被标识为shared的内存则会通过wp_page_reuse标记为wriable 因为谁先写不知道，所以两者都应该是wp，都能进行COW...这里产生了一个问题： 假如父子进程都使用COW，那么在子进程已经copy过的情况下，父进程再copy一次就会造成浪费。...COW 首先和常识相同，write这些页会触发page fault： handle_pte _fault linux使用handle_pte_fault函数处理： 如果vma是writable但是却触发了...总结 COW机制下，父子进程的页都会被标记为write protect 父子进程均有可能进行copy 最后一个写的进程不会进行copy，而是直接使用原本的物理页。
