Hmm. I don't know slqb well.
So, It's just my guess.
We surely increase l->nr_partial in __slab_alloc_page.
In between l->nr_partial++ and call __cache_list_get_page, Who is decrease l->nr_partial again.
After all, __cache_list_get_page return NULL and hit the VM_BUG_ON.
Comment said :
/* Protects nr_partial, nr_slabs, and partial */
spinlock_t page_lock;
As comment is right, We have to hold the l->page_lock ?

Hmm. I don't know slqb well.
So, It's just my guess.
We surely increase l->nr_partial in __slab_alloc_page.
In between l->nr_partial++ and call __cache_list_get_page, Who is decrease l->nr_partial again.
After all, __cache_list_get_page return NULL and hit the VM_BUG_ON.
Comment said :
/* Protects nr_partial, nr_slabs, and partial */
spinlock_t page_lock;
As comment is right, We have to hold the l->page_lock ?

Can you post your .config, please? I assume this is with CONFIG_NUMA?

Thank you so much for testing!
Nick seems to have gone silent for the past few days so I went ahead and
