Not sure what's more surprising: how long it took for NetBSD to
catch up to the rest of the BSDs (including UCB), or the amount of
code that NetBSD has claimed for itself without attributing to the
actual authors.

commands. Bump limit back to the standard 4, and at the same time eliminate
SDRETRIES and CDRETRIES (both defined to 4) in favour of a new define,
SCSI_RETRIES, also defined to 4.

SENSE_NOT_READY_BECOMING_READY sense errors. Some devices such as USB
Zip250 drives return the former when they mean the latter. Give the
first TEST UNIT READY command three times the usual retries so more
devices have time to get ready. This allows more removable devices to
detect media details and avoid issuing 'drive offline' messages.

RAW_PART will always be 0 -> disksize, so the bounds check will always
pass for i/o's to valid addresses. Now the i/o will be properly truncated
if it goes past the end of the device. This prevents various adverse
impacts of issuing i/o's for data past the end of the device.
Repeatedly requested by todd@.

that may run without interrupts, don't forget to add scsi_autoconf
to the flags and POLL for the result rather than wait for an interrupt that
will never come. Fixes Dale's Iomega Jazz drive on the ahc here, and no
doubt many other device combinations.

should fix a number of 'drive offline' situations where the device claims
it has no media loaded until the lock in occurs. Like a Blackberry Pearl
Todd Fries found and probably other USB devices. Move the lock in during
device open to before the test unit ready to eliminate similar spurious
rejections of the device.
Feedback from marco@, tests by todd@ and miod@.

geometry. But 63 * 255 > 2880 and the cylinder count becomes 0. So
if we end up with a valid disksize but 0 cylinders, set heads =
cylinders = 1 and sectors-per-track = disksize.

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
