Hi Anna-
Here's a fix for the bug reported yesterday morning, plus an
observability enhancement to help diagnose future similar bugs. The
fix needs to go into 5.6-rc and 5.5-stable as soon as you can. The
observability change can go in wherever you see fit. Thanks!
Changes since v2:
- Fix now passes the usual gamut of static checks
- Improve MR trace points even further
- Split out the trace point change; it does not need to be
backported
Changes since v1:
- Ensure the correct nents value is passed to ib_map_mr_sg
- Record the mr_nents value in the MR trace points
