Hi Guys, The 1st two patches move bvec iterator helpers out from bio.h, then they can be used even if CONFIG_BLOCK is disabled, so not necessary to use iov iter own approach to do the job. One motivation is that in the future we may support multipage bvecs, as interests[1] have been shown in this idea, so looks better to unify the implementation now.
