similar to: [PATCH 07/22] block: Convert bio_for_each_segment() to bvec_iter

More prep work for immutable biovecs - with immutable bvecs drivers won't be able to use the biovec directly, they'll need to use helpers that take into account bio->bi_iter.bi_bvec_done. This updates callers for the new usage without changing the implementation yet. Signed-off-by: Kent Overstreet <kmo at daterainc.com> Cc: Jens Axboe <axboe at kernel.dk> Cc: Geert

From: Wade Cline <clinew@linux.vnet.ibm.com> This patch is only an RFC. My internship is ending and I was hoping to get some feedback and incorporate any suggestions people may have before my internship ends along with life as we know it (this Friday). The filesystem should mount/umount properly but tends towards the explosive side when writes start happening. My current focus is on
