The comment leading into kmem_malloc (in sys/vm/vm_kern.c) is
worrying me:
* This routine has its own private kernel submap (kmem_map) and object
* (kmem_object). This, combined with the fact that only malloc uses
* this routine, ensures that we will never block in map or object waits.
Actually, this function is called by m_clalloc (in
sys/kern/uipc_mbuf.c) too. The comment is obviously wrong. Is it a
problem that this assumption is violated?
* Note that this still only works in a uni-processor environment and
* when called at splhigh().
The first part will be news to the folks running SMP. :-) The business
about splhigh is also wrong. But what worries me is that malloc calls
it at splmem, while m_clalloc calls it at splimp. Is that a problem?
