There has been some confusion since checkpatch started warning about bool

Many people feel there is still a legitimate place for bool in structures,
so provide some guidance on bool usage derived from the entire thread that
spawned the checkpatch warning.

Hey Jason,

I very much agree that the bool expectations could be much clearer, and this
patch is a nice step in that direction! Just a couple small nitpicks:

+Do not use bool if cache line layout or size of the value matters, its size
+and alignment varies based on the compiled architecture. Structures that are
+optimized for alignment and size should not use bool.

+Do not use bool if cache line layout or size of the value matters, as its size

Adding an "as" makes the sentence flow a bit cleaner: --------------

+into a single bitwise 'flags' argument and 'flags' can often a more readable

Missing a "be" here: -----------------------------------------

Ack from me after those two corrections.
