hi folks,
we have qstr data structure part in nameidata structure in name resolution.
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
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.

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.
