标题: LDD2书中的代码问题 [打印本页] 作者: jlfzx 时间: 2006-11-15 08:57 标题: LDD2书中的代码问题 在使用CONFIG_DEVFS_FS时，下面这个函数
scull_devfs_dir = devfs_mk_dir(NULL, "scull", NULL)
出现了以下错误
LDD/ldd2-samples-1.0.1/scull>insmod scull.o
Warning: loading scull.o will taint the kernel: no license
See http://www.tux.org/lkml/#export-tainted for information about tainted modules
scull.o: init_module: Device or resource busy
Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters.
You may find more information in syslog or the output from dmesg
