curproc was being used directly for ru_{in,ou}block counting. Instead
...
of using it directly, use a local, and set that local to be curproc
if curproc is not NULL else a pointer to process 0's proc struct.
If syncing disks while handling a panic that occurred while 'curproc'
was NULL, the old code would dereference NULL and die.

bdwrite() should upgrade writes to tape devices by sending them to
...
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.
