Hi,

These are few cleanups for the block trace.

Below is the test log on latest linux-block/for-next.

-ck

V2->V3:-
1. Rebase on block/for-next 5.11.

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 documentation
  block: get rid of the trace rq insert wrapper
