I suggest to improve the commit message.

* Are you still unsure about the next changes?
  https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/process/submitting-patches.rst?id=ae83d0b416db002fe95601e7f97f64b59514d936#n151

* Would you like to adjust the patch subject another bit?

* How do you think about to add the tag “Fixes”
  because of adjustments for the exception handling?


It can be nicer if all patch reviewers (including me) will be explicitly specified
as recipients for such messages, can't it?

Markus
