What's happens when that space is missing?
That's partly a request to add an impact statement, but also
for my education as I'm just learning all this shellcheck
stuff too.

BTW - if any of this was found using a tool, rather than
by inspection, please include a note of the tool used.

Thanks,
Alison

You added my Ack without addressing the feedback.

"Commentary on the impact of the change is always welcome."

Please include a sentence on how this triggered for you and some
analysis of the why it has not triggered previously. Otherwise "A space
is missing before ']'" does not add any information that can not be
determined by reading the patch.

A useful changelog for this would be something like:

Currently the cxl-region-sysfs.sh test runs to completion and passes,
but with syntax errors in the log. It turns out that because the test is
checking for a positive condition as a failure, that also happens to
mask the syntax errors. Fix the syntax and note that this also happens
to unblock a test case that was being hidden by this error.

I'm sorry about that. I thought this fix(syntax error) is too simple to say more.

It's a syntax error, so
'[ $ig -ne $r_ig]' is always false, it may hide the a real error.

shellcheck is able to inspect this error.

This time, they are all found by eyes :)
when i'm checking the full log when i met an error.


Thanks
