Ming Lei b59ea3efba block: don't optimize for non-cloned bio in bio_get_last_bvec() ... commit 90d0f0f11588ec692c12f9009089b398be395184 upstream. For !BIO_CLONED bio, we can use .bi_vcnt safely, but it doesn't mean we can just simply return .bi_io_vec[.bi_vcnt - 1] because the start postion may have been moved in the middle of the bvec, such as splitting in the middle of bvec. Fixes: 7bcd79ac50d9(block: bio: introduce helpers to get the 1st and last bvec) Reported-by: Kent Overstreet <kent.overstreet@gmail.com> Signed-off-by: Ming Lei <ming.lei@canonical.com> Signed-off-by: Jens Axboe <axboe@fb.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>		2016-03-16 08:43:01 -07:00
