Sir. Charles Manninq... I have a question about yaffs filesystem. I have 1~2 step. As follows. [1 step] create org.dat touch org.dat [2 step] Making Hardlink ln org.dat hardlink.dat this time, 2 step running...... What information in this "struct dentry *old_dentry" is already there? old_dentry of conten is dentry of org.dat? ..... dentry of org.dat... That was right? [ In yaffs_fs.c ] [ In yaffs_fs.c] static int yaffs_link(struct dentry *old_dentry, struct inode *dir, struct dentry *dentry) thank you.... Have a good time......
