Hello RT-list!
I'm pleased to announce the 5.10.204-rt100 stable release.
This release is an RT-only update.
The only change in this release is specific to RT:
rt: mm/page_alloc: backport missing bits from __build_all_zonelists() fix
A while ago upstream landed commit a2ebb51575828 ("mm/page_alloc: use
write_seqlock_irqsave() instead write_seqlock() + local_irq_save().")
to fix a problem that had already been worked on v5.10-rt via commit
7bdd3bd5143a4 ("Revert "mm/page_alloc: fix potential deadlock on
zonelist_update_seqseqlock""). Sebastian pointed out it was important
to backport the missing elements of a2ebb51575828 for code consistency.
You can get this release via the git tree at:

Hi!
We (as in cip project), are trying to do -cip-rt releases
once a month. Are there any plans for 5.10-rt release any time soon?
That would help us ;-).
Best regards,
Pavel

Hi Pavel!
I already pushed v5.10-rt-next (containing v5.10.209-rt101-rc1) to
kernel.org and kernelci should pick that up for comprehensive testing
within the next hour. As soon as the testing is done I will perform the
release dance.
My vacations started (abruptly) a few days before I planned and that lead
to some delays. People volunteered to run the builds if anything critical
popped up, but that was not the case.
Sorry for the inconvenience, I do hope a release tomorrow or Friday does
not disrupt your workflow too much.

No problem, thanks for the information, and looking forward to the
release.
