Since 3687fcb0752a ("btrfs: zoned: make auto-reclaim less aggressive")
commit and cc4804bfd639 ("btrfs: skip reclaim if block_group is empty"),
reclaim algorithm has been changed to be less aggressive, which breaks this
test.
The test has been adapted so that the new auto-reclaim algorithm can be
tested with the following flow:
- Write a small file
- Write a big file that crosses the reclaim limit
- Delete the big file
- Check that only the block group that contained the small file is reclaimed,
and the small file is relocated to a new block group.

Pankaj, this patch has not been integrated yet.
Could you please resend it?
Actually, I encountered an issue with this testcase where it worked
perfectly well for smaller drives, but started to fail for bigger ZNS drives.

Could you try it in your setup and see if it works correctly?
Right. I'm also facing some issues. However, the stack trace indicates
a memory error, which I attributed to my low-resourced nullb device.
I'm trying to emulate a zoned device using other methods, but I haven't
been successful yet.
Thanks, Anand
I remember Johannes also looked into this issue, but we never came to any conclusion.
