commit c4d56664a22f0c46ec0e81b856860964ea89f420

    Reduce fragmentation in the slab allocator
    
    This reverts a change brought when reworking slab lists handling that made
    the allocator store slabs in LIFO order, whatever their reference count.
    While it's fine for free slabs, it actually increased fragmentation for
    partial slabs.
    
    * kern/slab.c (kmem_cache_alloc_from_slab): Insert slabs that become partial
    at the end of the partial slabs list.

    Rename list_insert to list_insert_head
    
    This change increases clarity.
    
    * kern/list.h (list_insert): Rename to ...
    (list_insert_head): ... this.
    * kern/slab.c: Update calls to list_insert.
