Hi Mohit,

Please refer to ULK 3rd edition Section 12.5 pathname lookup, it says:

struct qstr      last         Last component of the pathname (used
when the LOOKUP_PARENT flag is set)

so if LOOKUP_PARENT is set, last refers to the last name components,
e.g. in /a/b/c it reference to c while path->dentry->qstr will refer
to b because you intended to lookup parent not the last component.
Note that path is an output parameter while last is input parameter.

To: kernelnewbies <redacted>


hi folks,


we have qstr data structure part in nameidata structure in name

resolution.

quoted

so it may work like this :

 nameidata->path->dentry->qstr.

it  is the real name component in a  path name for that directory ro file

(i

quoted

think so).

so what is  the need of having another qstr like:

namidata->qstr (ie. last)


in nameidata structure.
sorry ,it may seem  foolish to u guys but i ............

thanks in advance.
