oops on 6.11-rc4 loong64 with RST & subpage enabled.

Hi,
There is a oops when I am testing RST & subpage support.

My bad, in my patchset to add the subpage + zoned support, I added an
extra ASSERT() check to make sure that we didn't get compressin/inline
triggered.

But forgot that zoned write by itself will return 1, triggering that
ASSERT().

I'm already working on another patchset, mostly to prepare for subpage
sector perfect compression support, that will remove the ASSERT() and
the ret > 0 case completely.

Will definitely let you know when the patchset is finished.

Thanks,
Qu

It is better to post all output in the message itself, even if large - for
archiving purposes, as external websites may disappear later, and also for
better searchability.

If it is complex to deal with auto-wrapping in the client, then I'd suggest to
attach a .txt file.
