* DESCRIPTION
|
|
* 1. Use a component of the pathname, which is not a directory
|
|
* in the "path" parameter to statfs(). Expect ENOTDIR
|
|
* 2. Pass a filename which doesn't exist, and expect ENOENT.
|
|
* 3. Pass a pathname which is more than MAXNAMLEN, and expect
|
|
* ENAMETOOLONG.
|
|
* 4. Pass a pointer to the pathname outside the address space of
|
|
* the process, and expect EFAULT.
|
|
* 5. Pass a pointer to the buf paramter outside the address space
|
|
* of the process, and expect EFAULT.
|
|
* 6. Pass a filename which has too many symbolic links, and expect
|
|
* ELOOP.
