Hi,

I failed to use this reproducer to reproduce this problem.

kernel: 5.15.0-0.rc5
kernel config: CONFIG_TRANSPARENT_HUGEPAGE_MADVISE=y
mount option: rw,relatime,ssd,space_cache=v2,subvolid=5,subvol=/
btrfs souce: 5.15.0-0.rc5, misc-next

You also need CONFIG_READ_ONLY_THP_FOR_FS=y.

Thanks a lot.

This reproducer works well with CONFIG_READ_ONLY_THP_FOR_FS=y.
