...Do you have some idea about this? ... I think it is fairly normal... :(

We have a large number of managed workgroups, the current use case is the 4k compressed size,
each compressed page has a workgroup, but erofs also has reclaim paths to free them for low memory cases.

But since the structure (z_erofs_vle_workgroup, erofs_workgroup) is critical,
I need to make it as small as possible.

Thanks,
Gao Xiang
