Ilya Dryomov fc218544fb ceph: fix iov_iter issues in ceph_direct_read_write() ... dio_get_pagev_size() and dio_get_pages_alloc() introduced in commit b5b98989dc ("ceph: combine as many iovec as possile into one OSD request") assume that the passed iov_iter is ITER_IOVEC. This isn't the case with splice where it ends up poking into the guts of ITER_BVEC or ITER_PIPE iterators, causing lockups and crashes easily reproduced with generic/095. Rather than trying to figure out gap alignment and stuff pages into a page vector, add a helper for going from iov_iter to a bio_vec array and make use of the new CEPH_OSD_DATA_TYPE_BVECS code.
