Hi,
just got the following panic with today's -current sources and
an oldish config file (one not having "options SOFTUPDATES"):

    panic: softdep_slowdown called
    Debugger("panic")
    Stopped at      Debugger+0x45:  xchgl   %ebx,0xc05fa740
    db> trace
    Debugger(c026141c) at Debugger+0x45
    panic(c026ecc1,c66e1b94,c01ff565,c1cda000,0) at panic+0x7c
    softdep_slowdown(c1cda000,0,0,ffffffff,2) at softdep_slowdown+0xd

    syscall(2f,2f,2f,8254000,bfbffdc8) at syscall+0x231
    Xint0x80_syscall() at Xint0x80_syscall+0x1d

and in trying to track down the problem i noticed the following:

    > grep ffs_softdep conf/*
    conf/files:ufs/ffs/ffs_softdep.c        optional softupdates ffs
    conf/files:ufs/ffs/ffs_softdep_stub.c optional ffs

so the question is, do we still need ffs_softdep_stub.c ? In any
case, getting an explicit panic does not really sound right...

	cheers
	luigi
