Hi *,
I'm writing a module whose aim is to fetch some file
attribute (like stat(2) in userspace does).
I'm trying with the inode->i_op->getattr startegy, but
this looks like the getattr function is not availabe
(...)
Any help is welcome.
Here's the code:
-------------
struct nameidata *my_nd;
struct iattr *my_ia;
struct inode *inode;
struct dentry *d_entry;
int error;
if(path_init(d, LOOKUP_FOLLOW|LOOKUP_POSITIVE, my_nd))
error = path_walk(d, my_nd);
if(error || !(my_nd->dentry->d_inode))
printk("Problem with %s\n",d);
else{
d_entry = my_nd->dentry;
inode = d_entry->d_inode;
printk("got d_entry\n");
}
/* below here I always get to the "else" branch :(* */
if (inode->i_op && inode->i_op->getattr)
{
inode->i_op->getattr(d_entry, my_ia);
printk("got inside\n");
}
else printk("didn't get i_op OR getattr\n");
--------------
ciao,
- Zac
