EXPORT_SYMBOL

EXPORT_SYMBOL宏的作用是将符号导出到内核符号表，使得其他模块或内核可以使用该符号。在Linux内核中，通过使用EXPORT_SYMBOL宏可以将非静态函数和变量导出给其他模块使用。而EXPORT_SYMBOL_GPL宏则仅将符号导出给GPL许可的模块。在Linux 2.6版本之后，由于安全考虑，默认不再自动导出所有符号，需要使用EXPORT_SYMBOL宏来标记需要导出的符号。这样其他模块才能够使用这些导出的符号。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
