These can basically trigger in extremely low memory space and only when such ranges exist in the PA rbtree. Hence, I guess it is a little hard to tigger race.
Ritesh, thanks for looking into this!
Naresh, how easy is it for you to trigger the BUG when using LTP? I did two xfstests runs using "gce-xfstests -c ext2/default -g auto", one on the ext4 dev branch, and one on linux-next 20230717, and I wasn't able to trigger the BUG.
If you can trivially trigger it using LTP (perhaps with a low memory configuration in your test setup?), that would be useful to know.
Cheers,
