sent to the adapter instead of the 10 bytes the scsi_sychronize_cache
command actually occupies. This freaked out the ahc on jsing@'s SGI

called from the last sdclose() on a device will now reset SDF_DIRTY
after submitting the SYNCHRONIZE CACHE command. sddone() need not
worry about SDF_DIRTY since it was never called for the SYNCHRONIZE
CACHE command anyway.
This eliminates a spurious SYNCHRONIZE CACHE command being issued for
every sd device from sd_shutdown().

and a file is written onto the stick. Without these fixes the
machine panics or hangs.
The usb fix calls the callback when the stick is pulled out to free
the associated buffers. Otherwise we have busy buffers for ever
and the automatic unmount will panic.
The change in the scsi layer prevents passing down further dirty
buffers to usb after the stick has been deactivated.
In vfs the automatic unmount has moved from the function vgonel()
to vop_generic_revoke(). Both are called when the sd device's vnode
is removed. In vgonel() the VXLOCK is already held which can cause
a deadlock. So call dounmount() earlier.

"becoming ready" - this is done in the exact same way that it
was done for tape in st.c. This commit adds a cd specific interpret_sense
routine to cd.c that will catch the becoming ready case and handle it.
This also removes the need to use crazy timeouts to catch this case.

that specifies the version of SCSI being supported. Even the ANSI part
that we use is complex. 4 means 2, 5 means 3 and 6 means 4. Translate
and use the value correctly. Fixes SCSI5 and SCSI6 in dmesg. And
properly protects SCSI2 devices from getting SCSI3 commands.

prevents the issuing of sizing inquiries to non-existant or non-responsive

Also try to avoid *extremely* unlikely loop of scsi_start() commands, by

spoofed sd disklabels. Sectors are the partition size units used and
documented everywhere else in the tree. sd ensures a sector will
always be a multiple of 512.
