Hi Christian,

Before merging your patch, fstests has merged below commit:

  [1cca2bc0d7a9] fstests: vfstest: skip rejected tmpfile creation

I think we can revert this commit, then merge yours currently.


Your patchset below contains 2 patches:
  https://lore.kernel.org/fstests/20260615-overlay-idmapped-vfstest-v1-0-c6b3b2228092@kernel.org/

Patch 1/2 has been acked and contains fix we want I think, so I'll
merge it first. The patch 2/2 remains under review, so I'll leave
that one for you update later. Does this make sense to you?

Thanks,
Zorro
