Patch Set #1, Line 1832:
//sys Fsconfig(fd *int, cmd int, key string, value []byte, aux int) (err error)I don't understand why the fd argument is *int rather than int. But if it's really *int, then this won't work, because the type "int" has a different size for C and Go.

I don't understand why the fd argument is *int rather than int. […]
My fault, sorry, infidelity it should be int, not a *int, I tried it in runc (https://github.com/AlexeyPerevalov/runc/commit/e2f388c03014e0810d889bb9662dfab234e48fe5#diff-e0932af06cb46065b2ef5fc89bc2bd9b880c9578e01b89ef4ecaeffb78a8bef0L13), but when I copied func signature from https://lwn.net/Articles/802096/ I incidentally preserve *int.

Fsconfig couldn't implemented by generator, it requires
special cases handling.

fsconfig will be in the next patch, since too many questions with it.
