    SubjectRe: [RFC][PATCH] printk: Add %pb to print bitmaps

    There's a pretty widespread convention that %b is used to print in
    binary: printf("%b", 10) -> 1010. Regrettably it isn't part of
    standard C, but it's often supported anyway. Perl's printf does this
    as well. Perl uses %B also.

    If we later want to add binary printing to kernel print(), we'd presumably
    use %pb, to match this precedent.

    So perhaps it would be better to avoid consuming `b' for bitmaps?
