slub: remove kmalloc under list_lock from list_slab_objects() V2
list_slab_objects() is called when a slab is destroyed and there are
objects still left to list the objects in the syslog. This is a pretty
rare event.
And there it seems we take the list_lock and call kmalloc while holding
that lock.
Perform the allocation in free_partial() before the list_lock is taken.
