From d74c6d514fe314b8bdab58b487b25992291577ec Mon Sep 17 00:00:00 2001 From: Kent Overstreet Date: Wed, 6 Feb 2013 12:23:11 -0800 Subject: block: Add bio_for_each_segment_all() __bio_for_each_segment() iterates bvecs from the specified index instead of bio->bv_idx. Currently, the only usage is to walk all the bvecs after the bio has been advanced by specifying 0 index. For immutable bvecs, we need to split these apart; bio_for_each_segment() is going to have a different implementation. This will also help document the intent of code that's using it - bio_for_each_segment_all() is only legal to use for code that owns the bio.
