Revision 23688bf4f830a89866fd0ed3501e342a7360fe4f authored by Junichi Nomura on 22 December 2015, 17:23:44 UTC, committed by Jens Axboe on 22 December 2015, 17:26:53 UTC
blk_queue_bio() does split then bounce, which makes the segment
counting based on pages before bouncing and could go wrong. Move
the split to after bouncing, like we do for blk-mq, and the we
fix the issue of having the bio count for segments be wrong.
Fixes: 54efd50bfd87 ("block: make generic_make_request handle arbitrarily sized bios")
