redirection of console serial input (keyboard, mouse). Fixes non-redirection of
keyboard to X server on a 5k/240. The Mfb and sfb drivers are similarly broken.
write them to disk! From Keith Smith at Harvard, via Kirk McKusick.
fixes the occasional `blkfree: freeing free block' that has been seen
when cluster reallocation code is enabled.
to have the same interface as native readdisklabel(), call it cleanly
from caller of readdisklabel(), and fix bug that left d_npartitions at 1
for ultrix-compat labels. Ultrix labels now actually work.
(1) all Chinon CDS-431 CD-ROMs (regardless of revision)
are forced to only having LUN 0, at the suggestion
of Michael Hitch.
(2) _force_ searching of extra LUNs for the Emulex MD21/S2
ESDI bridge. It's pre-SCSI 1, but knows about LUNs.
"amazing." From Jason Thorpe.
(3) recognize an Emulex tape adapter in front of a QIC-36
tape, and have it forced to only LUN 0. This is
an odd one; vendor, name, and rev strings are all
spaces. Anything that mathes this is very likely
broken, anyway, so might as well give it a shot.
Again from Jason Thorpe.
bawrite(). it's logically more correct (doesn't return an error code,
because it's async; bdwrite is also async), it still writes things
in-order, it makes sure the proper accountins is done (see the
wasdelayed cases in bwrite()), and it allows writes to vnodes on volumes
mountd with the MNT_ASYNC to be converted into delayed writes the way
God, err, Kirk intended. Convert synchronous bwrite()s on MNT_ASYNC
file systems to delayed writes.
explained in comments), which can cause a race condition. amazingly,
the _only_ time i've ever seen or heard of this problem was in some
comments and sources by Rick Macklem, and when running against the
a DEC OSF/1 NFS server running on an Alpha.
pmax conf.c references them. A cut-and-paste job from the pmax
rzwrite() and rzread(). tzwrite() and tzread() are utterly untested.
tzwrite() should also check for write-protect, or handle writes to a
write-protected tape gracefully.
