Hmmm. Please help me out here: why was that fix queued for -next and not
for this cycle?

Was that patch when it was committed considered too dangerous for
mainlining this cycle (at this point of the cycle I guess it might)? I
mean, it's afaics (not totally sure here, the change is missing a Fixes:
tag as well as Closes: tags pointing to the report) fixing a regression
with f0551af02130 that Christian reported (see start of this thread, e.g.,
https://lore.kernel.org/all/12df8b45-6100-4c8b-b82a-a6a75bed2e05@xxxxxxxxx/
). And f0551af02130 is from v6.9-rc1, so given what Linus wrote in
https://lore.kernel.org/all/CAHk-=wis_qQy4oDNynNKi5b7Qhosmxtoj1jxo5wmB6SRUwQUBQ@xxxxxxxxxxxxxx/
that fix should likely have been (or still should be?) merged in this
cycle, unless it's really dangerous.

Or did I misunderstood something here?

Ciao, Thorsten
