Introduced by 7ef88ad5 (BUILD_BUG_ON: make it handle more cases), the
whole BUILD_BUG_ON stuff should be hidden behind #ifdef __KERNEL__, but
it's pretty harmless.

That's actualy a false positive, the header defines a prototype for the
quotactl() syscall.

That looks indeed bogus, there is no sdla() syscall.

As Vitaliy wrote, this is a leftover after 43a9907.

Nevertheless, these errors are pretty harmless, the prototypes do not
break parsing the header when compiling userspace programs.
