Dear Reviewers,
Here is a new version for this patch series.
We didn't get agreement on patch #4 (#5 in v2) in the former cycle though,
I made it based on my understanding. We can continue discussing on it.
Changelog:
v2->v3:
- #2. Reworded comment message.
- #4. Trace failure only, trace all error path, and a common knob for all
failure paths.
v1->v2:
- #1. Reworded commit message and comment, plus some typo fixes.
- #2. New patch.
- #3. Added the missing suggested-by Pierre.
Fixed typos.
Added sanity check on pa->pa_iova_pfn and updated comments accordingly.
- #4. Removed unused idaw_nr.
- #5. Replaced leading white spaces with TABs.
Traced the function in anycase.
