SubjectRe: [PATCH v2] arch: all: include: asm: bitops: Use bool instead of int for all bit test functions

Thank you all for your work. Commonly, I should send patch v3 for it.

And very sorry for replying too late. During these days I have no
enough time on it (working, buying house, and catching a cold, but I am
lucky enough that my father's health is OK).

Thanks.
