| H A D | vm_kern.c | diff 87157 Fri Nov 30 22:21:30 MST 2001 luigi vm/vm_kern.c: rate limit (to once per second) diagnostic printf when you run out of mbuf address space. kern/subr_mbuf.c: print a warning message when mb_alloc fails, again rate-limited to at most once per second. This covers other cases of mbuf allocation failures. Probably it also overlaps the one handled in vm/vm_kern.c, so maybe the latter should go away. This warning will let us gradually remove the printf that are scattered across most network drivers to report mbuf allocation failures. Those are potentially dangerous, in that they are not rate-limited and can easily cause systems to panic. Unless there is disagreement (which does not seem to be the case judging from the discussion on -net so far), and because this is sort of a safety bugfix, I plan to commit a similar change to STABLE during the weekend (it affects kern/uipc_mbuf.c there). Discussed-with: jlemon, silby and -net |
