Thanks for the profile. I still wonder where exactly thouse super-hot
call-sites are...
In this case, it's a typical network server
Each time a packet is sent to or received from network, network stack has to
allocate/free a skb (kmem_cache_alloc()/kmem_cache_free() and its data
(kmalloc/kfree)
Other paths are for example dentries allocations, file allocations, ... really
many spots for some workloads.
