|
|
* Test basic error handling of statx syscall:
|
||
|
|
*
|
||
|
|
* - EBADF - Bad file descriptor
|
||
|
|
* - EFAULT - Bad address
|
||
|
|
* - EINVAL - Invalid argument
|
||
|
|
* - ENOENT - No such file or directory
|
||
|
|
* - ENOTDIR - Not a directory
|
||
|
|
* - ENAMETOOLONG - Filename too long
