"2G". This mostly brings unit_adjust() in line with what is in du(1).

the wheel group has no explicit members listed in /etc/group. This adds
the "exempt_if_empty" flag to pam_wheel in the default configuration;
in some environments, it may be appropriate to remove this flag, however,
this default is the same as pre-pam_wheel.

to help clean up. After selecting a potential buffer to write, this
patch has it acquire a lock on the vnode that owns the buffer before
trying to write it. The vnode lock is necessary to avoid a race with
some other process holding the vnode locked and trying to flush its
dirty buffers. In particular, if the vnode in question is a snapshot
file, then the race can lead to a deadlock. To avoid slowing down the
buf_daemon, it does a non-blocking lock request when trying to lock
the vnode. If it fails to get the lock it skips over the buffer and
continues down its queue looking for buffers to flush.

NB: Open_Disk should redo how it malloc's memory so the caller can free
everything. Documentation says the caller can free the disk list to
reclaim everything but this leaks the indirect strings. Fixing this
is simple for the sysctl case but adds complexity to the fallback,
non-sysctl, case.
