Subject: bio: zero inlined bio_vec
From: Hugh Dickins <hugh@xxxxxxxxxxx>
bvec_alloc_bs() zeroes its bio_vec, and at least __blk_queue_bounce()
relies upon that: therefore bio_alloc_bioset() must zero the inlined
bio_vec - without that, lots of nastiness occurs in bounce_end_io and
blk_rq_map_sg and other places when booting up my PAE box.
