This might not be a right way to fix types since style(9) does not accept syntax changes.
`bool` (or `_Bool`) is C standard whereas `boolean_t` is not. This can cause problems in both userland and kernel.
An exemple of this is ioat.c, where `intrdelay_supported` and `is_submitter_processing` are supposed to be 0/1 bool values, but they are actually int behind the hood.
This means values other than 0/1 can be accepted, which is not a intended behaviour of `bool` type.
