This is a known issue, @jankara has a in-flight kernel fix.

For a record, it TCONF on 6.11, at least on ext4, with underlying btrfs:

FYI it's already merged to Linus' master branch: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=76486b104168ae59703190566e372badf433314b.

@metan-ucw Shouldn't we add the commit to the "linux-git" tags? Or should it wait till kernel 6.13 is released?

Hi!

@metan-ucw Shouldn't we add the commit to the "linux-git" tags? Or should it wait till kernel 6.13 is released?

We usually wait for the kernel to be released before we add tags to tests. Either way it's quite early in the 6.13 development process so it's possible that this may get reverted. So maybe wait at least for a few RCs before we add it as a tag.
