高版本linux內核添加yaffs2文件系統支持後編譯出錯

內核 移植 編譯時出現下面的錯誤沒法編譯，求解決方法。

make: *** [fs] 錯誤 2

出錯解決：

1.須要將mtd下的函數前加下劃線，例如mtd->read改成mtd->_read（只有yaffs_vfs.c yaffs_mtdif.c yaffs_mtdif1.c yaffs_mtdif2.c這幾個文件會出現這種問題）。

2.查看dache.c中這個函數已經改成了d_make_root，將d_alloc_root改成d_make_root。

3.end_writeback(inode)改爲clear_inode(inode)

其它問題可參考http://www.linuxidc.com/Linux/2012-07/64306.htm
