case there is nothing to do. This happens normally when the card shares
the interrupt line with other devices.
This code saves a couple of microseconds per interrupt even on a
fast CPU. You normally would not care, except under heavy tinygram
traffic where you can have some 50-100.000 interrupts per second...
On passing, correct a spelling error.
lookup vop so that it defaulted to using vop_eopnotsupp for strange
lookups like the ones for open("/dev/null/", ...) and stat("/dev/null/",
...). This mainly caused the wrong errno to be returned by vfs syscalls
(EOPNOTSUPP is not in POSIX, and is not documented in connection with
specfs in open.2 and is not documented in stat.2 at all). Also, lookup
vops are apparently required to set *ap->a_vpp to NULL on error, but
vop_eopnotsupp is too broken to do this.
current_file_name and current_link_name sometimes point into the
middle of malloc()ed memory and sometimes point to alloca()ed memory,
but free() is sometimes called on them. This seems to be harmless
for the usual tar operations, but it is usually fatal for `tar -W'.
E.g., for `cd /etc; tar Wcf /tmp/foo rc', at the start of
verify_volume(), current_file_name points to alloca()ed memory, and
tar attempts to free it.

register our sub-busses in the reversed order. In the future, we may provide
a hint to CAM on how to order the scans for multi-function adapters that also
set this flag, but trying to do it the "twin channel" way will lead to
a panic.

Use sysctlbyname() instead of sysctl().
Clear up and simplify the version extraction code.
Attempt to detect stretches of zeroes in the dump and avoid writing
them to disk to save space and time.
