block sizees larger than 8192 bytes have been resolved, as per the

rev 1.5 src/sys/boot/alpha/boot1/sys.c
than necessary.
o Move a rarely-used goto label inside a critical section so that we don't
perform an splnet() for which there is no corresponding splx().
o Remove unnecessary splnet()/splx() around accesses to kaioinfo::kaio_jobdone
in aio_return().
o Use TAILQ_FOREACH for simple cases of iteration over kaioinfo::kaio_jobdone.
functions just grab f_data and don't muck with anything else so this
should be ok.
this fixes a panic with invariants where it thinks we've doubly initialized
the filetmp mutex even though all we've done is neglect to bzero it.
vfs.nfs.iodmaxidle (idle time before nfsiod's exit). Make it adaptive
so that we create nfsiod's on demand and they go away after not being
used for a while. The upper limit is NFS_MAXASYNCDAEMON (currently 20).
More will be done here, but this is a useful checkpoint.

which was causing the link of the kernel to fail. Since layer4/i4b_l4mgmt.c
is always required by i4b and layer3/i4b_q931.c is only needed when a
passive card is present it makes sense to have the declaration in the
former file only.
No MFC required since the problem only became apparent after a change to
the compile options in -current which AFAIK wasn't made in -stable.

I've polished it quite a bit reducing the need for locking and
adapting it for KSE.
Locks:
1 mutex in each filedesc
protects all the fields.
protects "struct file" initialization, while a struct file
is being changed from &badfileops -> &pipeops or something
the filedesc should be locked.
1 mutex in each struct file
protects the refcount fields.
doesn't protect anything else.
the flags used for garbage collection have been moved to
f_gcflag which was the FILLER short, this doesn't need
locking because the garbage collection is a single threaded
container.
could likely be made to use a pool mutex.
1 sx lock for the global filelist.
struct file * fhold(struct file *fp);
/* increments reference count on a file */
struct file * fhold_locked(struct file *fp);
/* like fhold but expects file to locked */
struct file * ffind_hold(struct thread *, int fd);
/* finds the struct file in thread, adds one reference and
returns it unlocked */
struct file * ffind_lock(struct thread *, int fd);
/* ffind_hold, but returns file locked */
I still have to smp-safe the fget cruft, I'll get to that asap.
Clarify comment about kind of color emulators for which vt*-co* entries

Use direct \E[m instead of ...;m for dumb emulators.
that va_mode of the supplied attributes is filled in with a valid
file mode (i.e not VNOVAL, and only ALLPERM bits set). However,
some NFS server op functions didn't guarantee this for all possible
request messages:
If a V3 client chose not include to a mode specification, we could
end up creating an ffs inode with mode 0177777, requiring a manual
fsck on the next reboot. Fix this by setting va_mode to 0 before
calling the VOP if a mode hasn't been supplied by the client.
In nfsrv_symlink(), S_IFMT bits supplied by a V2 client could end
up in the va_mode passed to VOP_SYMLINK with similar effects. We
now use the macro nfstov_mode() to correctly mask the bits.
motherboard chipsets. We need to force the chip to reload its MAC address
into the receive filter, and enable software access mode for the PHY.

lost if some other process uses the lock while we are sleeping. We
restore it after we have slept. This functionality is provided by
a new routine interlocked_sleep() that wraps the interlocking with
functions that sleep. This function is then used in place of the
old ACQUIRE_LOCK_INTERLOCKED() and FREE_LOCK_INTERLOCKED() macros.

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.
