semantics of the nfsm_reply() macro were changed so that the caller
has to explicitly handle the V2 error case, whereas before,
nfsm_reply() did a `goto nfsmout' then. A few server ops (setattr,
readlink, create, mkdir) weren't updated to match, so errors in the
V2 case could cause protocol hangs and leaked mbufs.
Correct some comments that describe the old nfsm_reply behaviour.
[older, harmless nit] Remove the unnecessary `nfsmreply0' label in
nfsrv_create(), since for its users, the main `ereply' label does
the same thing.
but since the nfs cleanup, it hasn't done so in the case where
`error' is EBADRPC. Callers of this macro expect it to initialise
*mrq, and the `nfsmout' exit point expects a reply to be allocated
if error == 0. When nfsm_reply() was called with error = EBADRPC,
whatever junk was in *mrq (often a stale pointer to an old reply
mbuf) would be assumed to be a valid reply and passed to pru_sosend(),
causing a crash sooner or later.
Fix this by allocating a reply even in the EBADRPC case like we
used to do. This bug was specific to -current.
intermodule communication is done via kobj calls. If anything
currently depends on them, let it break so that we can fix it. Maybe
we'll need to export some of the card_if.c or power_if.c symbols, but
I think those should be in the base kernel (since all *_if.c should be
in the base kernel for just these reasons).
in softdep_sync_metadata(). Otherwise we may miss dependencies
that need to be flushed which will result in a later panic
with the message ``vinvalbuf: dirty bufs''.

larger than 8k. We now use 4k buffers regardless of the filesystem
block size, so there is no longer a static limit.
Simply increasing the buffer size from 8k to 16k as done on the
i386 doesn't work on the alpha, probably because it causes us
to overshoot boot1's 48k runtime memory limit.

is correct but less than useful. There is some uncertainty about whether
isblank() is in C99, but it is certainly not in C90. It just conforms
to C89 because it is a conforming extension.
back (as of man.c,v 1.45), change the meaning of the -m option
from poorly documented and badly coded "alternate system" to a
much more useful "different architecture for the same system".

defined, no symbols are exported from the module. This is
the typical configuration for most device drivers and
standalone modules; only infrastructure modules or those with
special requirements typically need to export symbols.
Don't print the objcopy commands as they are run when converting
symbols; they're bulky and annoying in many cases.
All the alpha loaders should use the same version file. Also, we might
should merge the various loaders (cdboot, loader, netboot) into one loader
that can boot off of disks, CD's, and network devices. The version bump
is needed so the FICL scripts won't bomb out thinking that the netboot
binary is too old.

We calculate a trigger point that both guarentees we will find a
sufficient number of vnodes to recycle and prevents us from recycling
vnodes with lots of resident pages. This particular section of
code is designed to recycle vnodes, not do unnecessary frees of
cached VM pages.
