Commit Message

Jonathan Cameron Sept. 13, 2023, 3:05 p.m. UTC
Michael Tsirkin observed that there were some unnecessarily
long lines in the CXL code in a recent review.
This patch is intended to rectify that where it does not
hurt readability.

This whole series can be picked up into trivial-patches tree
(whcih is getting ready to be pushed to master).

I've reworked patch 2 as you made some good points about the
changes making unclear code even more unclear.

Also, I have this on top of a series that touches the same bit
of code.  For me landing that is more important than this, hence
the ordering of the series.

Hopefully Michael Tsirkin will pick up v2 along with the
other series, or whcih can take this in the future once the
dependency is in place.

You that is.  I briefly imagined there was someone using the
tag whcih :) 

Friday evening is my excuse...

Too much code review today it seems.
