Subject: [PATCH v3 0/4] vfio: ccw: error handling fixes and improvements
Date: Wed, 23 May 2018 04:44:58 +0200	[thread overview]
Message-ID: <20180523024502.94244-1-bjsdjshi@linux.ibm.com> (raw)

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.
