Hi Christian,

Thanks for your feedback and for applying this patch to the vfs-7.0.misc branch!

I tried to locate the commit in vfs/vfs-7.0.misc (and also searched by subject),
but I couldn’t find it yet.

Subject:
fs/file: optimize close_range() complexity from O(N) to O(Sparse)

Is the patch still in your local queue / pending push, or did it land with a
different commit hash after a rebase?

Just wanted to double-check the current status.
Thanks again for the review and for taking the patch.

Best regards,
Qiliang
