Finally, we find the problem:

https://github.com/torvalds/linux/commit/8343b1f8b97ac016150c8303f95b63b20b98edf8
https://github.com/torvalds/linux/commit/65161c35554f7135e6656b3df1ce2c500ca0bdcf

In the first patch:
   They thought `err' is not used at all, and removed it.
In the second patch:
   They add it back and a wrong value "-EINVAL" is given.

Better KPI got.
