[PATCH V4 15/45] block: rename bio_for_each_segment* with bio_for_each_page*

Ming Lei
2017-12-18T12:26:39Z

It is a tree-wide mechanical replacement since both bio_for_each_segment()
and bio_for_each_segment_all() never returns real segment at all, and
both just return one page per bvec and deceive us for long time, so fix
their names.

This is a pre-patch for supporting multipage bvec. Once multipage bvec
is in, each bvec will store a real multipage segment, so people won't be
confused with these wrong names.
