Updated the kernel, the function now waits indefinitely. Probably the timeout was rounded down to INT_MAX, but I can't tell as it's in the kernel.

For reference, looks like Linux performs some additional validation on the usec field:

sec = LONG_MAX, usec = 0: ok
sec = LONG_MAX, usec = 999999999: ok
sec = 0, usec = 1000000000: EINVAL
