Merge tag 'block-6.17-20250925' of git://git.kernel.org/pub/scm/linux/kernel/git/axboe/linux
Pull block fixes from Jens Axboe:
"A regression fix for this series where an attempt to silence an EOD
error got messed up a bit, and then a change of git trees for the
block and io_uring trees.
Switching the git trees to kernel.org now, as I've just about had it
trying to battle AI bots that bring the box to its knees, continually.
At least I don't have to maintain the kernel.org side"
