I fear it's still a bit premature for enable SU+J by default. Rather
recently I was told about a SU+J filesystems lost after a panic

provide some more details) and I'm pretty sure I've seen the problem
described in PR 149022 also after the potential fix mentioned in its
feedback.

I tried enabling SU+J on my /var (after backing up of course) and after
a panic random files were missing entirely. Not the last updates to
those files, the whole file, and many of them had not been written to in
days/weeks/months.
With all due respect to the hard work that went into the code, I would
be very uncomfortable with enabling it by default at this point.

With all due respect, how can we fix things that nobody reports?
If you have a problem, let us know about it. And of course, we
need something more specific than the above.
I have not been following current but I read any emails sent directly to
me without a mailing list in the cc. I also was not aware of this. I had
not heard of any filesystem corruption problems at all. If there are any,
I also am not comfortable with enabling it by default. I want to fix that
first.
I have blocked off next week to work on this. I already sent an email out
to current@ requesting bug reports. Please if you have anything else let
me know immediately so I can prioritize it and start investigating.
Thanks,
Jeff
