Please use "bool X:1" instead of "u8 X:1". I think it was a bad idea
to make
checkpatch complain about "bool X:1" since "bool X:1" should only be
avoided
in structures for which alignment must be architecture-independent. For struct
device it is fine if member alignment differs per architecture. Additionally,
changing "bool X:1" into "u8 X:1" will reduce performance on
architectures that
cannot do byte addressing.
I generally agree. But the checkpatch warning _could_
be useful in those cases where alignment should be
architecture-independent.
Any suggestion on how to improve the message?
