I guess it was removed after 2.6.6 . And now this function is called
as user_path. Look at the following commit which can give you some
idea.
commit 2d8f30380ab8c706f4e0a8f1aaa22b5886e9ac8a

[PATCH] sanitize __user_walk_fd() et.al.
...
...
+asmlinkage long compat_sys_statfs(const char __user *pathname, struct
compat_statfs __user *buf)
{
- struct nameidata nd;
+ struct path path;
int error;
- error = user_path_walk(path, &nd);
+ error = user_path(pathname, &path);
if (!error) {
struct kstatfs tmp;
- error = vfs_statfs(nd.path.dentry, &tmp);
+ error = vfs_statfs(path.dentry, &tmp);
if (!error)
error = put_compat_statfs(buf, &tmp);
- path_put(&nd.path);
+ path_put(&path);
}
...

Don't worry, most people here are friendly :) They won't kick your butt just because you're asking too much or too hard. Most likely, you'll be ignored if your question is either OOT or nobody knows the answer :) > I want the Definition of "user_path_walk()" function, If any one had, Please > send it and if not, can any one tell me where could I find it. Hmm, strange, online code explorer at lxr.linux.no (specificly, the one which indexes 2.6.32) can not find such function. Which kernel function do you refer, anyway? However, just guessing, perhaps that function took a complete path as its parameter and returns the related inode that corresponds to it? And maybe...it is named "walk" because the functions iterates it from root directory down to the directory which owns the file. Of course, as always, inode and dentry cache are looked up first. -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecar...@nl.linux.org Please read the FAQ at http://kernelnewbies.org/FAQ
