At time of filesystem superblock initialization, the root dentry d_op is set if the corresponding filesystem wants. Likewise on (name resolution) that traps into filesystem lookup, u initialize the d_op for the dentry corresponding to that name. Also u happen create or instantiate the dentry, at that time u can initialize the d_op if required. thx,thayumanavar s. -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to [email protected] Please read the FAQ at http://kernelnewbies.org/FAQ
