arm_linux_yaffs2文件系统移植到内核GUN编译错误问题处理

yaffs2更新的比较慢,跟不上内核的更新速度.所以只能自己做些修改

first step

刚开始从官网下载下来的直接打补丁后会出现一系列的错误.如下:

上面有三个问题要解决

∙1: error: ‘struct file’ has no member named ‘f_dentry’

∙2: error: ‘new_sync_read/write’ undeclared here

∙3: error: implicit declaration of function ‘nd_set_link’

1 ‘struct file’ has no member named

‘f_dentry’
