From 62a8067a7f35dba2de501c9cb00e4cf36da90bc0 Mon Sep 17 00:00:00 2001 From: Al Viro Date: Fri, 4 Apr 2014 23:12:29 -0400 Subject: bio_vec-backed iov_iter New variant of iov_iter - ITER_BVEC in iter->type, backed with bio_vec array instead of iovec one. Primitives taught to deal with such beasts, __swap_write() switched to using that kind of iov_iter. Note that bio_vec is just a triple - there's nothing block-specific about it. I've left the definition where it was, but took it from under ifdef CONFIG_BLOCK. Next target: ->splice_write()...
