属性在用户空间的C代码中是很罕见的,但是内核中却很普遍。所有标记为__init的,会在初始化后释放内存以供重用(还记得那条过去内核的那条“Freeing unused kernel memory…[释放未使用的内核内存……]”信息吗?)。__exit表明,当代码被静态构建进内核时,该函数可以安全地优化了,不需要清理收尾。最后,module_init()...

kernel的source code中有很多使用pr_debug/dev_dbg输出的日志信息(例如device tree解析的代码,drivers/of/fdt.c)。默认情况下,kernel不会将这些日志输出到控制台上,除非: 1)开启了DEBUG宏,并且 2)kernel printk的默认日志级别大于7 看似简单,不过我相信每个人都问过这样的问题(不管是问自己还是问别人,特别是在调...
Freeing unused kernel memory: 448k freed 如果提示VFS错误,则是Linux内核编译的时候没有开启ext2的配置,可以回到make menuconfig中开启这个选项。 /bin/ash: can't access tty; job control turned off 如果提示job control,则需要回到busygox编译那里关闭这个选项。
