Below is the test log on latest linux-block/for-next. Last two patches are needed to for testing. -ck V1->V2:- 1. Add fixes tags. 2. Move EXPORT_TRACEPOINT_SYMBOL_GPL(blk_rq_insert) to block/blk-core.c. 3. Add reviewed-by tags. 4. Remove the null_blk patches fro now, create a separate series. Chaitanya Kulkarni (5): block: remove superfluous param in blk_fill_rwbs() blktrace: add blk_fill_rwbs documentation comment blktrace: fix blk_rq_issue documentation blktrace: fix blk_rq_merge
