[PATCH] bio_clone fix
Fix bug introduced in 2.6.11-rc2: when we clone a BIO we need to copy over the current index into it as well. It corrupts data with some MD setups. See http://bugzilla.kernel.org/show_bug.cgi?id=4946 Huuuuuuuuge thanks to Matthew Stapleton <matthew4196@gmail.com> for doggedly chasing this one down.
