softupdates as mount option?

[Ivan Voras <ivoras@xxxxxxxxxxxxxx>]

I asked around in freebsd-current list about making softupdates a mount 
option, and it seems that it can't be done because of backward 
compatibility and licencing issues (and/or because "Kirk said so"). 
Since it is implemented in NetBSD (and at a very early stage, someone 
said 3 years ago), the patches (also posted to freebsd-current) are 
smallish, and DFBSD is not burdened by backward compatibility issues, 
maybe it's a good idea to implement it as such?

I'm not 'pressing the issue', and it is not a big deal, but would be 
convenient to have it as a mount(8) option (like sync and async) instead 
of something completely external to it.

(If anyone wishes to do it, I suggest reading the pro and con 
disucussion(s) at freebsd-current before starting)
